389 directory server attribute changing to null value


I have recentlly migrated edirectory to 389 director y server everything is working fine.
But while creating new user from customer side the user creation is working only by giving a value in attribute pan if not giving value in attribute pan it will not create.
So please suggest how to make the pan attribute null

how to make attribute pan non- mandatory

The main page for 389 Directory Server has a link for contacts – probably the best place for questions about 389 Directory Server.
