[tac_plus] PAM and LDAP with non-root user

[Ben Wiechman]

Various threads document that when using PAM for authentication the tac_plus
has to run as root due to requirements of the pam_unix.so module. Those
threads maybe indicate that if LDAP was used the server could run as a
non-root user. Is it possible to integrate with LDAP using PAM and run
tac_plus as a non-root user or am I interpreting those threads incorrectly?
