I create the user in iManager.

Then enable LUM for the user.

User are associated to universal password with configuration to allow
admin to retrieve password.

Enabling samba fails with Name space error MISSING_MANDATORY_ATTRIBUTE.

additional informations:

samba domain object is at organisation level.

Please help me.
thanks ...
