How Do I Reset A Lost Weblogic Admin User Password?

by Shiva Molabanti

You installed OBIEE 11G and you did not write down the Weblogic Domain admin password, or you’ve had it installed for a while and can’t remember what the password is to get into the WebLogic Admin console to make a change.  This post will help you do that so you can get on with your business.

1. Make sure all the services are down

2. change directory to <Middleware_Home>/user_projects/domains/bifoundation_domain/bin

cd <Middleware_Home>/user_projects/domains/bifoundation_domain/bin

3. Source the setDomainEnv.cmd(Windows) / setDomainEnv.sh (Linux) script so we can get all the WebLogic variables set correctly

In windows: setDomainEnv.cmd

In Linux: . setDomainEnv.sh

4. Now change the directory to security directory in your instance.

cd <Middleware_Home>/user_projects/domains/bifoundation_domain/security

5. Move the DefaultAuthenticatorInit.ldift to a backup file

In Windows:

mv DefaultAuthenticatorInit.ldift DefaultAuthenticatorInit_old.ldift

In Linux:

mv DefaultAuthenticatorInit.ldift DefaultAuthenticatorInit_old.ldift

6. Run the “java weblogic.security.utils.AdminAccount newuser newpassword .” to generate a new DefaultAuthenticatorInit.ldift with a new user with the assigned password within the security directory

eg: java weblogic.security.utils.AdminAccount weblogic weblogic123 .

Note: replace newuser and newpassword with a user and password of your choosing. Ensure the password is a minimum of 8 characters and contains at least one numeric character. Also, don’t forget the period “.” at the end of the above command, it is required.

7. Change directory to <Middleware_Home>/user_projects/domains/bifoundation_domain/servers/AdminServer/security

cd <Middleware_Home>/user_projects/domains/bifoundation_domain/servers/AdminServer/security/

8. Edit the boot.properties file and replace newpassword and newusername with the user and password you defined in step 6. Do this for all the servers in the domain.

password=newpassword

username=newusername

The boot.properties will get encrypted once the admin server starts up

9. Rename or remove directory <Middleware_Home>/user_projects/domains/bifoundation_domain/servers/AdminServer/data/ldap as it will get recreated once the WebLogic Admin server starts.

e.g:

rename <Middleware_Home>/user_projects/domains/bifoundation_domain/servers/AdminServer/data/ldap <Middleware_Home>/user_projects/domains/bifoundation_domain/servers/AdminServer/data/ldap_OLD

10. Change directory to <Middleware_Home>/user_projects/domains/bifoundation_domain/bin and start the Weblogic Admin Server

In Windows: startWebLogic.cmd

In Linux:  ./ startWebLogic.sh

11. Once the weblogic server is up, you’ll be able to login to Console with the new weblogic Admin user and password.
