Netscape Directory server V6.21

[Netscape Directory serv]

Hi,

I am not able to delete an entry from directory server.I am getting the error "ldap_delete: Operation not allowed on nonleaf". However when i do ldapsearch the output shows that no entry exist below the above entry.And when i try to add some entry below it than it gives me error nosuchobject and "dn2entry: the dn was in the entrydn index (id 791), but it did not exist in id2entry" in the error log. Please help me in this regard.

Thanks,
Sandy
