AttributeError: type object ‘object’ has no attribute ‘identify’

Reason for the issue is bug 49838. The new udm objects are registered in ldap  for UCS versions >= 4.4-0, but the udm refactoring was done in 4.4-0e101:
b46919b37109 | Bug #48390: unify identify() method

Workaround: Update affected systems to 4.4-0e101 or higher
