Say that I make a user resource...
user { 'test':
ensure => 'present',
groups => 'some_group'
}
If you vagrant ssh into that machine, what would be the default password for test user -> su test?
By default, a newly created user will have no password, and it will not be possible to log in as the user. If you want to set a password, you need to specify the password property of the user resource.

how can we reset the username and password in windows for Jenkins.
or is there a way to uninstall Jenkins completely so that when I reinstall it , I can again create a username and password?
Any solutions would be very much appreciated
Option 1
You can simply delete the entire JENKINS_HOME directory and then restart the server. This will prompt you to the new setup wizard.
Option 2
Open JENKINS_HOME/config.xml and disable security by setting the following.
<useSecurity>false</useSecurity>
Then access Jenkins and open the Script Console(JENKINS_URL/script). Execute the following script to create a new user.
import jenkins.model.*
import hudson.security.*
def j = Jenkins.getInstance()
def realm = new HudsonPrivateSecurityRealm(false)
realm.createAccount("newadmin","newpass")
j.setSecurityRealm(realm)
j.save()
Now enable security again and login to Jenkins with the new user.
Additional
If you want to recover the old user. After following the above steps open the file JENKINS_HOME/users/newadmin_RANDOM_NUMBER/config.xml and copy the following two values seed and passwordHash to the old admins config.xml(If the old admins username is admin the file should be located at JENKINS_HOME/users/admin_RANDOM_NUMBER/config.xml)
<jenkins.security.seed.UserSeedProperty>
<seed>405397d771ce33e7</seed>
</jenkins.security.seed.UserSeedProperty>
and
<hudson.security.HudsonPrivateSecurityRealm_-Details>
<passwordHash>#jbcrypt:$2a$10$UGYgHccQxAd9V6neqfJxx.......</passwordHash>
</hudson.security.HudsonPrivateSecurityRealm_-Details>
Then restart the server and you should be able to use the password of newadmin for admin.
I tried using Jenkins or my admin username as user and password. For password, I tried to update using sudo passwd jenkins, so I am fine on that. However, I am skeptical about the user name. How do I confirm the username for Jenkins? Can someone pls help me?
During the initial run of Jenkins a security token is generated and printed in the console log. The username is admin
The token should look something like,
*************************************************************
Jenkins initial setup is required. A security token is required to proceed.
Please use the following security token to proceed to installation:
41d2b60b0e4cb5bf2025d33b21cb
*************************************************************
For me the initial admin password was in a log at ~/.jenkins/secrets/initialAdminPassword
after installing with homebrew.

If you pod is running in a Kubernetes cluster, just look at the running process … Your initial password will be shown…
e.g.
--argumentsRealm.passwd.admin=**3kJQtPDkhk** --argumentsRealm.roles.admin=admin
Username: admin
For password,
cat /Users/$(whoami)/.jenkins/secrets/initialAdminPassword
you will get similar to this token 2762710d8dab4c88a59fea0a2e559069
I am trying the host name as user name and password as entered during installation. The login screen in CLI keeps on giving incorrect login error. How to login?
The default username for elastistor is root.
Use the password as configured during installation.
I have just install Postgres 9.3 on Windows 7. The installation completed successfully. It has never asked me to provide the password for postgres user.
The service postgresql-x64-9.3 is up and running. However, I cannot connect: I do not not know the password. I've found the following answer, but it did not help:

might work for windows too
After installing postgres follow following steps in order to setup password for default system account of Linux execute following in terminal:
user:~$ sudo -i -u postgres
postgres#user:~$ psql
after executing above two commands you will get into postgres shell
Execute this query in postgres shell:
postgres=# ALTER USER postgres PASSWORD 'mynewpassword';
your new password is 'mynewpassword' without quotes and now you can connect with external GUI tools like DBeaver
WARNING: trust means exactly that. Anyone who can connect to the PostgreSQL server can control it. If you set trust mode that allows superusers like user postgres (or all users) to connect, they get total control of your PostgreSQL and can probably run shell commands too. You should usually only use it to change the password then restore the configuration back to the auth mode you were using before.
If you used an unattended installer script, the password will be in the script or associated config file.
Otherwise, treat it the same as if you lost/forgot the password rather than never knowing it:
Edit pg_hba.conf, setting the auth mode to trust instead of the default md5
In the Services control panel restart the PostgreSQL service
Connect with psql or PgAdmin or whatever
ALTER USER postgres PASSWORD 'mynewpassword';
Edit pg_hba.conf again and set the auth mode back to md5
Restart PostgreSQL again
pg_hba.conf is in your data directory. By default it'll be %PROGRAMFILES%\PostgreSQL\9.3\data.
To edit it you'll have to use the security tab to give yourself read/write permissions (via a UAC prompt). This might require you to set yourself as the owner of the file.
On unix systems it's more secure to prepend a
local all all peer
line to pg_hba.conf and then sudo -u postgres psql (assuming your PostgreSQL server runs as user postgres) to get an interactive psql session without using a password. That way you don't have to use trust.
On initialisation you can access the DB as:
Username: postgres
Password: postgres
By default user postgres does not have a password
Start psql and create a password:
sudo -u postgres psql
\password postgres - It will ask you enter a password for user postgres
Through trial and error I found that the password for Postgre SQL 10 for the username postgres is "admin". I kept typing in different password until I reached that password. I am using pgAdmin 4 to test out my SQL Statements, POSTGRE SQL 10 is the first server connection set up using localhost.
It seems there was no default password, but psql wouldn't accept a lack of a password (fe_sendauth: no password supplied). To get around this, I opened pgAdmin, then in the left sidebar:
Servers
Login/Group Roles
Right click postgres and click Properties,
Go to Definition tab
Set the password in the Password field
After saving, psql accepted that password. There may have been a switch I could have supplied to have it accept a lack of a password (--no-password?), but the user should probably have a password anyways, so this seemed reasonable.
go to control >> computer management >> Locaol users and group >> users >>
right click on openpgsvc >> set password.
after that now you can access with this password on openpgsvc
The simplest solution I've found is just to install PgAdmin and connect to the local server with the current Windows credentials (username + password). Then you can change the password to the postgres user.
step1: Go to control panel
Step2: Click on Administrative Tools
Step3: Click on Computer Management
Step4: There under "Local Users and Groups" Double click on user
Step:5: then right click on postgres and you can set password

I had installed IBM DB2 Content Manager 8.4.1 months ago and now I wanted to access it to continue some more work.
But when I try to log in using System Administration Client, it tells me the password is expired. The error is:
DGL0394A: Error in ::DriverManager.getConnection;[jcc][t4][2012][11248][3.50.152]
Connection authorization failure occurred. Reason: Password expired.
ERRORCODE=-4214,SQLSTATE=28000 (STATE) : ;
[SERVER = icmnsldb, USERID = icmadmin, SQL RC = -4214, SQL STATE = 28000]
I've tried looking thru the config files, using the java update command line.. and I can't find a way to change or reset the password. I can't use System Administration Client to change the passwords, since it won't log me in to begin with. Any other method I can use to reset/change the password for a DB2 CM user?
DB2 uses the operating system to authenticate users, so you need to use the OS tools to reset the icmadmin user's password. Your post is tagged as Windows, so look for the icmadmin user in either the local machine or in the domain if your server belongs to a domain.
Just use the Client for Windows on a desktop machine and not the eClient to login. It will directly notify about a expired password and you can set the new password immediately.
I faced the same issue. I logged in as root and chaged the password for db2 user by passwd . and changed in the WAS console. It worked.
In Windows, click on start > Control Panel > User Accounts > User Accounts > Manage User Accounts.
Here, select the DB2 username and click on Reset Password.
If you are on Docker, you need to perform a docker exec into the DB2 container (Linux) and then change the password for the local user that you are trying to log in to DB2 with. In my case, the name of the user was "myuser". I changed the password by executing
passwd myuser
Note that you are root by default when you exec into the container. Else use
docker exec -u root <containerName> /bin/sh
