Adding new entry into Active Directory from webMethods


I am trying to add new entry into active directory through webMethods. webMethods runs under unix environment while active directory is residing under windows 2003 server. I am always getting :

LDAP: error code 16 - Error in attribute conversion.

When I try to enter data through java client, it works fine. I just can’t figure out what the reason is ?

I would really appreciate if somebody can help me out.
