Kerberos and Multiple UPN

Hello Guys,

How do you deal Kerberos groups authentication and multiple UPN ?

My users in the same UPN are correctly identified but users from others UPN not.

Try several things and nothings works (account-key-processing/filter)

How should I define Kerberos users, groups, servers ?

Completely lost, if you have a template somewhere it will be perfect.

Many thanks for your help
