[SOLVED] Courier-Imap - Courier-Authlib - PAM Problem

It took me most of a day and half of the night, but I finally have it working.

The symptoms:

1) emerge update
2) etc-update config changes were minor
3) SMTPauth and courier-imap no longer work

The Investigation:

Logfiles report imap-ssl failed to authenticate: imapd: LOGIN FAILED, user=blahblahblah

I turned on full debugging in authdaemonrc. Full debugging is friggin' useless. It reports no useful information, only username and attempted password which I knew for a fact were good.

Trying to run authtest against courier-authlib gave the error: Authentication FAILED: Operation not permitted

Debugging reported error: undefined symbol: nscd_flush_cache

Attempted solutions:

I deep emerged older versions of saslauthd, courier-imap, courier-authlib which worked previously but no longer worked. I installed courier-imap and courier-authlib from current source and got the same error. I cursed and swore. I considered wiping Gentoo and installing Ubuntu. Despite exhaustive searches on this forum and lots of people with the same or similar problems, nothing I found worked.

The Holy Grail:

I finally found a site (http://squarism.com)that described a solution to the exact problem I was having and gave a credible explanation. Courier-authlib has a problem in that courier-libpam builds and links to undefined and weak symbols such as nscd_flush_cache. All version 0.57 builds may exhibit this problem. The solution is to mask 0.57 and emerge the older 0.55.

Try this:

# echo ">=net-libs/courier-authlib-0.57" >> /etc/portage/package.mask
# emerge courier-authlib

BINGO!! My IMAP, IMAP-SSL now work. In the past, I have found lots of valuable information to solve problems, so this is my attempt to contribute...

Wow.... I've tried everything I have found... nothing worked... but courier-pop3d worked for me, so courier-imapd must work too. That was the solution. Thanks.

Don't know if this is what you are after, but I changed the default authmodulelist in /etc/courier/authlib/authdaemonrc to

Changing the authmodulelist setting to authpam only worked for me! Thanks!

Thanks for the help.

I just like to add a few things. I emerged down authlib .55 and it still didn't work but when i edited authdaemonrc for the "authpam" and restarted courier-authlib it not only restarted that service but the other couriers such imap. Right away that told me everything was working and sure enough i was able to get my email. So i then emerged back to .58 and made sure "authpam" was not commented out and that worked as well. Basically it looked like all I needed to do was uncomment "authpam"
