Every time you attempt to launch the application, LDAP Administrator displays the following error message box:
CAUSE
This problem may be caused by different reasons like unexpected application or system shutdown. Besides LDAP Administrator version 3.3 Xmas edition (3.3.0.1438) has a bug that may corrupt database while importing LDAP Browser / Administrator 2.X profiles what makes the application unable to start immediately after its installation or upgrade.
WORKAROUND
If you have version 3.3 Xmas edition installed, it’s strongly recommended to switch to a newer version. If upgrade does not help please remove the metabase.stg file.
