Installed new server, 6.5 sp4a, then migrated a Netware 5.0 sp6a server.

Clients cannot login, NMAS: Invalid requested sequence error -1660
I checked Console One, and the schema was not extended.
I manually created all the items listed in TID 10077551. Clients still
could not login unless they un-installed NMAS.

So, I deleted the objects that I created and un-installed NMAS.

Workstations with the new clients still cannot login--same errors.
Workstations using client 4.83 can login.
Only option I see is to un-install NMAS on all 850 client workstations.

Any other suggestions?
