Were those users created in 11.01 or have they disappeared after an upgrade? Have they been created recently? Are you really sure the "Finish" button has been clicked to update the user database? What do you see with "omniusers -list"?

OK, that's a different story. Let's check this step by step. The first step has been:

omnicc -secure_comm -regenerate_cert xxxxxx

So I understand this was run on the cell server and xxxxxx was the name of another server. Is this indeed what was done? Please confirm.

In that case I would rerun it with the name of the cell server:

omnicc -secure_comm -regenerate_cert <CS_FQDN>

This will generate the correct localhost certificate on the cell server again. Next you will need to run:

omnicc -secure_comm -reconfigure_peer <CS_FQDN>

on all clients. Please let us know the status after that.

In that case I would rerun it with the name of the cell server:

omnicc -secure_comm -regenerate_cert <CS_FQDN>

This will generate the correct localhost certificate on the cell server again. Next you will need to run:

omnicc -secure_comm -reconfigure_peer <CS_FQDN>

on all clients. Please let us know the status after that.

we are not looking to regenerate that certificate, as it would bring us the problem again - there is no other way to solve the user issue.
