Overview

pam_db helps you to build and administrate a mail-server without creating a passwd-entry for every mail account.

Prerequisites

• Linux-PAM (it works at least with version 0.66)
• qpopper 2.53
• MTA: exim or sendmail
• Python >= 1.4

Installation Notes

• untar pam_db-x.y.tar.gz
• $EDITOR Makefile and edit it according to your needs
• make
• su
• make install or just manually copy the files...
• configure PAM authentication for qpopper in /etc/pam.d/qpop as in etc.pam.d/qpop
• untar qpopper2.53
• apply the supplied qpopper PAM patch
• Edit the uid and gid values (currently set to 8) which should be used for PAM mail accounts (they are set in pop_pass.c, about line 655). If you are using sendmail as MTA they must match the setting 'O DefaultUser' in sendmail.cf.
• compile qpopper: make 'O_DEFS=-DLINUX -DPAM' 'LIBS=-lcrypt -lpam -ldl'
• install qpopper
• Edit your MTA configuration to add /etc/aliases.mailusers.db as an additional aliases file
• reconfigure your MTA: kill -1 mta.pid

FAQ

Why is there no script for ...?

I have no need for it (or maybe haven't had time to write it) and nobody has contributed it.

I can't access the password database from (Python|sendmail|exim|qpopper)?

Maybe one of your components uses a different database library. Make sure all your components use the same database library and version.

Why is there no documentation?

I don't get paid for writing documentation for this program... :-)
