I am running ZCM 10.3.1 server(s) connecting to a oracle 10g database. We are in the middle of migrating our user authentication source from edir to AD, and I am at the point of wanting to remove the ZCM user source to edir - however when I go into the ZCC > Configuration > select the edir user source > Delete. After a short period of time I get this error:

Object delete failed.: com.novell.zenworks.datamodel.exceptions.InternalD ataModelException: org.hibernate.exception.GenericJDBCException: error performing bulk delete

at the top of the ZCC window

Has anyone seen this before? What can I do? :(
