========================================================================
Root Cause:
Issue can be due to corrupted LDAP. It's stuck at security/embedded LDAP start.

========================================================================
Resolution:
1. Login to admin server host
2. Take back up of $DOMAIN_HOME/servers/<SERVER_NAME>/data/ldap directory.
3. Restore ldap from working backup file $DOMAIN_HOME/servers/<SERVER_NAME>/data/ldap/backup
     OR
    We can start welogic admin server and ldap direcotry will get automatically created.
    Kindly note if you restart admin server without restoring ldap, all users access will get revoked except weblogic user.
