Hi
Some clarification to provide you with the best info possible:
Kerberos is a protocol that can be used by PAM. Are you going from PAM to Integrated
Widows Authentication using Kerberos for single-sigon?
This paper provides some information on that topic:
"Kerberos and SAS® 9.4: A Three-Headed Solution for Authentication"
http://support.sas.com/resources/papers/proceedings13/476-2013.pdf
SAS Note:
http://support.sas.com/kb/49/432.html
That might be a good start.
Best
