Bugzilla Bug 3218

The uw-imap ebuild generates /etc/pam.d files that do not use pam_stack.so

From /var/tmp/portage/uw-imap-2001a-r1/image :
xabbu image # cat etc/pam.d/imap
#%PAM-1.0
auth       required     pam_pwdb.so shadow nullok
account    required     pam_pwdb.so
session    required     pam_pwdb.so

From /var/tmp/portage/courier-imap-1.4.5/image :
#%PAM-1.0

# This is a sample authpam configuration file that uses pam_stack
# (circa linux-pam 0.72).

auth       required     pam_nologin.so
auth       required     pam_stack.so service=system-auth
account    required     pam_stack.so service=system-auth
session    required     pam_stack.so service=system-auth

Solution:

Replace /usr/portage/uw-imap/files/imap.pam with:

auth       required     pam_nologin.so
auth       required     pam_stack.so service=system-auth
account    required     pam_stack.so service=system-auth
session    required     pam_stack.so service=system-auth
