pam_alias - map user names using an arbitrary file

pam_alias is a PAM module which provides a way to map user names using an arbitrary file.

For example, it can rewrite mail address- or jid-style user names to local user names.

  foo@sub.example.org	loclfoo

will map the user name foo@sub.example.org to loclfoo, which will then be used in turn by the following PAM modules.

Installation

make install

Add something like this to the beginning of select PAM configs:

auth required pam_alias.so file=/etc/security/useralias

For more details, see the pam_alias(8) manual page.
