Users can change their OBIEE passwords without having Administrator privilege…follow the below steps to achieve it.
1. Copy controlmessages.xml from C:\OracleBI\web\msgdb\messages to C:\OracleBI\web\msgdb\ customMessages directory.
2. Open the copied version i.e. from C:\OracleBI\web\msgdb\ customMessages directory.
3. Uncomment the above selected line of HTML code and save the file.
4. Restart the OBIEE Services
5. Log in as a user who wants to change his/her password, click “My Account”, a popup will open and there will be link to change password.
Hope it helps…
