Can someone explain why SCCM require and UPN for the field Alternate subject name ?
You must configure the Subject Name for Build from this Active Directory information, and then select Common name for the Subject name format, clear the DNS name and select the User principal name (UPN) for the alternative subject name.
If my understanding is right the RADIUS athentication for Workstation authentication requires à FQDN / Common Name ? So why does SCCme ask for an UPN ?
Additional information :
The DNS name in the subject alternate name is used for vlan mapping at the Cisco ACS.
