[Bug 483170] [NEW] insufficient access permission for /var/run/courier/authdaemon

[Michael Jastram]

Public bug reported:

Binary package hint: courier-authlib

Summary:

The directory /var/run/courier/authdaemon had permission 750.  In order
to get courier-mta to work, I had to change it to 755.

Details:

I am running a mail server with imap and smtp, both served by courier.
Configuring imap was fairly straightforward.  Configuring smtp (with
courier-mta) gave me a headache.  The following simple test failed:

root at pluto:/etc/courier# echo "To: michael at localhost" | sendmail 
ERR: authdaemon: s_connect() failed: Permission denied
450-Service temporarily unavailable.
450 Headers specify no receipients.
sendmail: Unable to submit message.

This was strange for two reasons: First, I didn't expect sendmail to
communicate with authdaemon, and second, authdaemon worked just fine for
imap.

it took me a long time to find out that not all processes had access to
the authdaemon socket.  The socket itself had proper permissions:

root at pluto:/var/run/courier/authdaemon# ls -l
srwxrwxrwx 1 root root 0 2009-11-15 17:55 socket
...

... but the folder containing it didn't:

root at pluto:/var/run/courier# ls -l
drwxr-x--- 2 root   root     100 2009-11-15 17:55 authdaemon
...

A chmod to 755 of the containing directory did the trick.  I am not sure
whether this is the best solution (vs. changing ownership of the
folder).
