LDAP authentication via PAM is refused (and no logs are generated) when UsePrivilegeSeperation is enabled. Disabling PrivilegeSeperation fixes this, though sacrafices the benefits of PrivilegeSeperation. Normal unix authentication through PAM is unaffected - only pam_ldap experiences this problem. Can be duplicated under Debian Linux, Woody release.
Are you sure that this is not a pam_ldap bug?
