reset weblogic password

Steps to create another superuser in weblogic (when password of existing user is lost)

1. Shutdown WebLogic Server (If Running) – Optional Step

2. Login to WebLogic Server and set environment variable

cd $DOMAIN_HOME/bin   (where DOMAIN_HOME is directory in which your domain exists, default value is $MW_HOME/user_projects/domain/base_domain)

. ./setDomainEnv.sh

3. Create a initialization file using command

java weblogic.security.utils.AdminAccount   .  (Note the DOT at end of this command)

For Example

java weblogic.security.utils.AdminAccount weblogic welcome1 . (Note the DOT at end of this command)

This will create file  DefaultAuthenticatorInit.ldift in directory from which you executed this command .

4. Move file DefaultAuthenticatormyrealmInit.ldift  from $DOMAIN_HOME/security/ and replace it by  DefaultAuthenticatorInit.ldift generated in step 3

5. Move data directory under $DOMAIN_HOME/servers//datato another directory like data.bak (data directory contains files related to embedded LDAP and role mapping file). Replace with WebLogic Server like AdminServer and managed server. Repeat this step for all managed servers which are part of this domain.

This step will remove all existing users/groups from WebLogic’s embedded LDAP server (recreate these users/groups in setp8)

6.Recreate boot.properites (if any) under $DOMAIN_HOME/servers//security with username and password created in step 3 above like
USERNAME=weblogic
PASSWORD=welcome1

7.Start (or restart) Admin Server and test if you can login to weblogic console using new username and password. 

8. Recreate any users/groups(which were part of default authenticator prior to new super user creation) or import existing users (from weblogic’s servers embedded LDAP server backup)
