Environment

Novell BorderManager 3.8
Novell Modular Authentication Services
RADIUS

Situation

Error: NMAS -1639 Invalid Operation
Error was seen in the Radius debuglog.
No user was able to authenticate.

Resolution

We removed the sequences that where not needed like Universal Smart Card and only left in the sequences that where actually used for Radius NMAS authentication.

Additional Information

On the Login Policy object where you can define the rules for the Dial Access System object all available sequences where selected and tight to the rule with an enforcement of mandantory.
These sequences included Universal Smart Card method as well.
For an authentication request that comes in a user then need to fullfill all the defined sequences before he is allowed through.
