Description of problem:
imap-200c-1.5.0.i386.rpm has no /etc/pam.d/pop or /etc/pam.d/imap file,
which makes it unusable on PAM enabled RH 5.2 system.
Steps to Reproduce:
1.install imap-2000c-1.5.0.i386.rpm file
2.you will see what happened pretty soon
As a workaround, using the pam auth file from the previous release
appears to fix this ok. Please use that until a new errata is released.
