JHBPJF,
Here is the response from HP Level 2 Support:
We were able to replicate the issue at engineering lab and working with R&D for solution. Meanwhile, we recommend customers to remove all LDAP users/local non-admin users before try to upgrade HPDM from v 4.6 to v 4.7.
Thanks,
I replied asking for a work around for users who upgraded and are now stuck.
