I would like to use pam authentication to connect ldap users without adding thoses user to the system.In /etc/pam.d/webmin  : auth        required      pam_env.so debugauth        sufficient    pam_ldap.so config=/etc/ldap.webmin.conf    use_first_pass debugauth        sufficient    pam_unix.so nullok try_first_pass debugauth        requisite     pam_succeed_if.so uid >= 500 quiet(...)Even if a user is identifiable in the ldap, pam try anyway pam_unix.so.  How can I get why (bad password, unknown user, ...) from pam_ldap?
/etc/pam.d/* How to pam_ldap output debug?
pam;webmin
