+ A Name Service Switch (NSS) plugin is a shared library used by glibc
+ to -- among other things -- translate between usernames and numeric
+ userids and between group names and numeric groupids.
+ .
+ The libnss-afs library is an NSS plugin which answers these queries
+ using the information stored in the AFS ptserver, avoiding the need to
+ duplicate (and update) this information in /etc/passwd or LDAP. The
+ library also synthesizes the name AfsPag-XXXX for the fake group ids
+ that are used to represent AFS PAGs.
