I am trying to access the Github repo which sits behind an enterprise firewall (Open VPN). I am trying to access with my username and password but getting the below Exception. Any suggestions on how to access the repo with Spring Cloud.
application.properties:
spring.cloud.config.server.git.uri=https://github.com/company-repo/abc.git
spring.cloud.config.server.git.username=tarun
spring.cloud.config.server.git.password=xxxxx
spring.cloud.config.server.git.ignore-local-ssh-settings=true
Exception:
Error occured cloning to base directory. org.eclipse.jgit.api.errors.TransportException:
https://github.com/company-repo/abc.git: not authorized
Do not Use Your GitHub password in your app.prop file...You will get a Not Authorized exception. Instead Generate an access token.
Creating a personal access token
You should create a personal access token to use in place of a password with the command line or with the API.
Personal access tokens (PATs) are an alternative to using passwords for authentication to GitHub when using the GitHub API or the command line.
If you want to use a PAT to access resources owned by an organization that uses SAML SSO, you must authorize the PAT. For more information, see "About authentication with SAML single sign-on" and "Authorizing a personal access token for use with SAML single sign-on."
As a security precaution, GitHub automatically removes personal access tokens that haven't been used in a year.
Creating a token
Verify your email address, if it hasn't been verified yet.
In the upper-right corner of any page, click your profile photo, then click Settings.
Settings icon in the user bar
In the left sidebar, click Developer settings.
In the left sidebar, click Personal access tokens.
Click Generate new token.
Give your token a descriptive name.
Select the scopes, or permissions, you'd like to grant this token. To use your token to access repositories from the command line, select repo.
Click Generate token.
Click to copy the token to your clipboard. For security reasons, after you navigate off the page, you will not be able to see the token again.
Warning: Treat your tokens like passwords and keep them secret. When working with the API, use tokens as environment variables instead of hardcoding them into your programs.
To use your token to authenticate to an organization that uses SAML SSO, authorize the token for use with a SAML single-sign-on organization.
Using a token on the command line
Once you have a token, you can enter it instead of your password when performing Git operations over HTTPS.
For example, on the command line you would enter the following:
$ git clone https://github.com/username/repo.git
Username: your_username
Password: your_token
Personal access tokens can only be used for HTTPS Git operations. If your repository uses an SSH remote URL, you will need to switch the remote from SSH to HTTPS.
If you are not prompted for your username and password, your credentials may be cached on your computer. You can update your credentials in the Keychain to replace your old password with the token.
The way i made it work is :
Generate the Access Token on Github repo and provide read and admin rights to it
Use the Token as password
Credentials can be saved in Kubernetes as Secrets or inside Vault. Hope this helps.

I'm trying to create a Spring Cloud Config Server to retrieve configuration files from a private GitHub repository. My GitHub account has 2 Factor Authentication activated so I wasn't expecting the below configuration to work, which it didn't but I can't find any documentation to suggest what I need to do in order to make it work.
What configuration do I need to set that will allow the connection to work?
spring.cloud.config.server.git.uri=https://github.com/DanBonehill/photo-app-config
spring.cloud.config.server.git.username=USERNAME
spring.cloud.config.server.git.password=PASSWORD
Error
org.eclipse.jgit.api.errors.TransportException: https://github.com/DanBonehill/photo-app-config: not authorized
What you could try and do (have not tested this), is create a personal access token from the Github console.
Then configure
spring.cloud.config.server.git.username=<yourusername>
spring.cloud.config.server.git.password=<yourtoken>
Instead of using username and password you should use an ssh key, the official documentation can guide you through it!
Basic authentication using a password to Git is deprecated and will soon no longer work. Visit https://github.blog/2020-12-15-token-authentication-requirements-for-git-operations/ for more information around suggested workarounds and removal dates.
you solve this in 2 minutes, this problem is because at August 13, 2021 the github update the login form, to solve this.
1) login in your gitHub folow this path: Settings > Developer settings > Personal access tokens > Generate new token
2) Now set a long time to expiration token, check the "repo" to allow access repository with this token, and Generate token.
3) Now skill your github password because this token created is your new password, replace this at all application, server, terminal that need to access github.
4) Now configure your spring configuration server, this is a content of file "application.properties" of spring configuration server at path /src/main/resources/application.properties.
spring.cloud.config.server.git.uri= https://github.com/"username"/"repository" //your githur repository
spring.cloud.config.server.git.search-paths= myFilesFolder /if your files is into some folder
spring.cloud.config.server.git.username= testUsername // your username
spring.cloud.config.server.git.password= gti_FdsweecSoUSHPsdfw //Here is your new token created
Trying to figure out how to force command-line git to use Github token. If I clone repository with user name and token like git clone https://<user>:<mytoken>#git.web.com/organization/repositorythen everything works fine.
When I try to clone without the user name or token then the operation fails with an error:
remote: Password authentication is not available for Git Operations.
remote: You must use a personal access token or SSH key.
I would like to store that token somewhere so that I would not have to give it to git every time. Where should I store the token?
I tried to add token variable to a [user] section in .gitconfig file but it did not work.
Tried unsetting and setting (wincred) credential helper but that did not work either.
You should enable a credential manager, such as wincred, and then when Git prompts you for the username and password, enter the username and your token as the password. Git will then tell the credential helper to save the password in the system credential store, and future operations to the same server will reuse those credentials.
This is much more secure than using the token in the URL, because the system credential store is encrypted, whereas the file containing the URL is not.
It may be the case that you already have invalid credentials saved for that remote which are causing the failure; if so, see this answer for instructions on how to remove them so Git prompts you again, and then follow the steps above.
I have an auth server built using spring boot oauth2.0 and follows david_syer model.
My auth server does following -
Let user login via third party oauth provider like google or let user create his account on our server using username and password and generate token.
So, when user uses external oauth like google to login then I simply store the token and pass the same(google) token to my UI app for accessing resource api servers. I have an authentication filter that verifies token and allow api access.
When user uses username and password to get token we store user and his permissions and generate a token for him. Now UI uses our auth servers generated token to access resource api servers.
Now my question is
Is this the correct way of using token from external api and using the same to access our resource api server?
And how do I add authorities to user who are signing up using 3rd party oauth provider since I don't add user entry and authorities for them?
So, spring security which loads user and user authorities (loadUserByUsername() from UserDetailsService) will not have any thing if user came from eternal provider.
I have a suggestion for step 2:
After the user uses the google authentication, and gets redirected back to your application page, do the claims transformation on your server and generate your own token issued by the identity server that you have.
The reason is you will be able to provide specific claims and the claims names does not necessarily required to match up.
That way you keep verifying your own token all the time on the client app. So lets say the user uses Facebook instead of Google and even in that scenario as you will assign your own token, you need not to verify the token coming from different third party Identity servers.
That way, your identity server trusts Facebook, Google provided token and your application will trust only your identity server so your app doesn't need to know about what IDP is issuing the token.
And with the approach I suggested above, you will be able to even modify the claims for the user on your own and don't have to depend upon the third party identity server to provide claims.
I am using spring boot for backend and Android device for frontend of my system.
Right now I am facing the challenge to use Spring-OAuth2 to secure my resource server.
I have some questions, which I want to discuss with you:
My knowledge + this tutorial are saying that I should use the OAuth2.0 "password" grant type for my mobile app to obtain an access token. The official spring tutorial for security gives an example how to obtain the access token using password grant type:
$ curl client:secret#localhost:8080/oauth/token -d grant_type=password -d username=user -d password=pwd
And here comes my first question: Is there any possibility to obtain access token using the password grant type without sending the "client secret" ?
Since the client secret could be "reverse engineered" by decompiling the client app. The obtaining access token without secret should be somehow possible, because Facebook SDK for Android also does not need the client_secret in the mobile app.
I think here I have a little trouble understanding why the clientID + clientSecret needs to be included in the request above, because, since there are already username + password included, it should be possible to generate the access token, so does this brings a next level of security ? and does it implies the following (example): I am logged in as Filip in my Android client and I am sending the access token A with each request to the server. Then I log in as Filip into web client and I try to access the resource server from web client using the access token A, which is not possible because access token A was issued only for Android client ?
The next question is how can I refresh the obtained access token ?
I was trying to do so using the command below, but I got "Full authentication is required to access this resource." After I got the new refreshed token, can I use the refresh token to refresh my new access token again ?
curl -v --data "grant_type=refresh_token&client_id=acme&client_secret=acmesecret&refresh_token=REFRESH_TOKEN" http://localhost:9999/uaa/oauth/token
Thank you
The OAuth 2.0 spec allows for so-called public clients i.e. clients that don't authenticate themselves. So it is possible to use the Resource Owner Password Credentials grant with a public client, i.e. one that does not need to send a client secret. It does mean that the Authorization Server cannot assume anything about the client since a client_id is not a secret and there's no way to prevent a malicious client using this grant type or clients from impersonating each other. So using it in this way comes at the cost of reduced security although one may argue that in your case there's no way to use confidential clients anyhow, so there's no difference.
In general the Resource Owner Password Credentials grant is an anti-pattern for OAuth and only meant for migration purposes because it defeats most of the goals of OAuth in itself.
Access tokens are issued on a per-client basis.
You refresh token request seems OK but the Authorization Server may require basic authentication instead of providing the client_id/client_secret as post parameters, considering that you did the same for the original access token request.
I've deployed my site in IIS 7, and can browse to it fine on the web server.
I've set it to windows authentication (only), and when browsing from outside the domain, I want to be challenged for credentials, and gain access when entering a domain\username & password combination that exists in the AD.
401 - Unauthorized: Access is denied due to invalid credentials. My iis logs
I put a dummy site in IIS and set it to anonymous, I can browse to this no problem also.
I checked that windows auth was installed/set up on the web server, and it is.
What set of config parameters do I need to get this working?
*yes, I know I should use some sort of custom authentication provider with accounts stored in a database, but I don't want to go through that yet.
Thanks for any advice, words of wisdom.
I think your only option is to enable basic authentication. The user should then enter the full domain\username with the password. Beware though that basic authentication uses just base64 which can be very easily decoded. So if you enable basic authentication you have to use SSL/TLS as well.
In Internet Explorer, you can get it to prompt you by: Internet Options > Security > Custom level > User authentication > Logon > Prompt for username and password.
