User Mapping: Could not save logon data

Hi

I have installed EP6 NW04 SP9 on an AIX system with DB2 database and I'm trying to assign mapping data (user & password) to users through User Administration -> User Mapping option.

When I try to save it, the portal shows the message: Could not save logon data.

During the installation I imported the Cryptography toolkit with strong encription so the property ume.usermapping.unsecure is set to false.

Would it be possible somebody to help me please.

Thanks
