Kerberos authentication for AIX Version 5.3 Network File System Version 4
http://www.ibm.com/developerworks/aix/library/au-kerberonfs.html Depending on the requirement, you can either choose to use the UID-based credentials cache, which is common to all processes for a given user, or a PAG-based credential cache unique to a process. Likewise, either you'll need to make use of the UID-based AIX APIs or the PAG-based AIX APIs to form the credential cache file that store the Kerberos credentials - But PAG based is more granular.
Hope this helps
