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.
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.
