If Weblogic Administrator Password is lost How to change it ?

August 13, 2010

Worked for me on 10.3.2 and 10.3.3 (Fusion Middleware 11g)

Files invovled in changing password

1. DefaultAuthenticatorInit.ldift located in $ORACLE_HOME/user_projects/domains/YourDomainName/security
2. DefaultAuthenticatormyrealmInit.initialized located in $ORACLE_HOME/user_projects/domains/YourDomainName/servers/AdminServer/data/ldap

Weblogic Domain administrator username and password is stored in DefaultAuthenticatorInit.ldift

When Admin server is started default it checks DefaultAuthenticatorInit.ldift file for authentication.

Steps to recover password

1. Setting environment for the domain you want to change the password

$ cd $ORACLE_HOME/user_projects/domains/yourdomain/bin

$ . ./

2. shutdown the WLS Admin server.

$cd $ORACLE_HOME/user_projects/domains/yourdomain/bin


3. Change to security directory and remove DefaultAuthenticatorInit.ldift file

$cd $ORACLE_HOME/user_projects/domains/YourDomainName/security

$rm DefaultAuthenticatorInit.ldift

4. create DefaultAuthenticatorInit.ldift file in security folder

$cd $ORACLE_HOME/user_projects/domains/YourDomainName/security

$java weblogic weblogicadmin .

(Dot in the end of the above line indicates current directory)

Above java command creates DefaultAuthenticatorInit.ldift file

5. Delete DefaultAuthenticatormyrealmInit.initialized in $ORACLE_HOME/user_projects/domains/YourDomainName/servers/AdminServer/data/ldap

6. Start the weblogic server cd $ORACLE_HOME/user_projects/domains/YourDomainName/bin


7. Want to put in nohup then you need to change the password in files which you need to change is located in  $ORACLE_HOME/user_projects/domains/YourDomainName/servers/AdminServer/security/

If you dont have security directory in Adminserver create one and touch file and add username and password of webloigic administrator
