Comment 3 for bug 1343489

From /etc/login.defs:

#
# Which fields may be changed by regular users using chfn - use
# any combination of letters "frwh" (full name, room number, work
# phone, home phone). If not defined, no changes are allowed.
# For backward compatibility, "yes" = "rwh" and "no" = "frwh".
#
CHFN_RESTRICT rwh

Asking your system administer to change this to 'frwh' should suffice.

Thanks
