Manully Change the WebLogic Security Authenticator Type

It's triggered by a configuration mistake on LDAP authenticator provider. I was trying to register the OpenLDAP store with Weblogic Server. But by mistake, I chose "LDAPAuthenticator" as the provider type  which should be "OpenLDAPAuthenticator".

I didn't realize the mistake until I restarted the Admin server and got the errors - "JPS-00027: internal error You configured a generic WLS LDAPAuthenticator".

Caused By: JPS-00056: Failed to create identity store service instance idstore.ldap.provider:idstore.ldap. Reason: JPS-00027: internal error You configured a generic WLS LDAPAuthenticator.
The identity store type cannot be determined. Please choose an LDAP Authentication provider that matches your LDAP server.

<Sep 26, 2012 11:03:39 AM CDT> <Notice> <WebLogicServer> <BEA-000365> <Server state changed to FAILED>
<Sep 26, 2012 11:03:39 AM CDT> <Error> <WebLogicServer> <BEA-000383> <A critical service failed. The server will shut itself down>
<Sep 26, 2012 11:03:39 AM CDT> <Notice> <WebLogicServer> <BEA-000365> <Server state changed to FORCE_SHUTTING_DOWN>

So the admin server cannot be started because of the wrong authenticator type. But here is how to manually change the authenticator type. Target $Domain_HOME/config/config.xml, you will find the following line:

The fix is to replace "wls:ldap-authenticatorType" with "wls:open-ldap-authenticatorType". What it does is to switch the authenticator type from LDAPAuthenticator to OpenLDAPAuthenticator. Here you go, start the admin server and the error is cleared.
