Red Hat Bugzilla – Bug 117850
PAM Service Name doesn't match Actual PAM Filename in RPM
Last modified: 2007-11-30 17:10:38 EST
Description of problem: Postfix, when configured to use SASL, and SASL is set to PAM, uses the wrong "PAM Service Name". The Postfix documentation says it uses a name of "smtp" and indeed it does. _However_, the RPM provides a file named /etc/pam.d/smtp.postfix, which would require a "PAM Service Name" of "smtp.postfix". Version-Release number of selected component (if applicable): postfix-2.0.11-5 How reproducible: Every time. Additional info: I don't care which, but either Postfix should use a service name of "smtp.postfix" or the file in /etc/pam.d should be renamed from smtp.postfix to smtp. When I do the latter on my system, everything begins working as expected.
The file /etc/pam.d/smtp is shared with the other mta, sendmail. Did you use alternatives to set your mta to postfix? If you did then the file /etc/pam.d/smtp should be present, but will be a symbolic link to the postfix version. You should see something like this if you used alternatives, do you? If so this shouldn't be a problem and the bug can be closed. # ls -l /etc/pam.d/smtp /etc/pam.d/smtp -> /etc/alternatives/mta-pam # ls -l /etc/alternatives/mta-pam /etc/alternatives/mta-pam -> /etc/pam.d/smtp.postfix Use of alternatives is documented in /usr/share/doc/postfix-*/README-Postfix-SASL-RedHat.txt, although perhaps it needs to be called out better to make it more obvious.
I haven't heard anything back. I'm proceding on the assumption this problem arose from not using alternatives and I'm closing the bug out.
Yes, I didn't use alternatives (didn't even know it existed until your email). When I installed Fedora I selected Postfix as the MTA but it installed both Sendmail and Postfix anyway. I then did an "rpm -e sendmail" and assumed things would start using Postfix. I've now run the alternatives command to formally "set" things to Postfix, but I'm not sure how anyone would figure this out by themself.
Its in the chapter "Mail Transport Agent (MTA) Configuration" http://www.redhat.com/docs/manuals/linux/RHL-9-Manual/custom-guide/ch-switchmail.html 2 notes: All this tool does is call alternatives, and RHL-9 is the current doc set for Fedora
