We use mantistouch and LDAP auth.
And we have a problem with the new users because they can't login until they aren't login to the mantis "normal" version.

We made a patch for it in the core/authentication_api.php:

function auth_attempt_script_login( $p_username, $p_password = null ) {
global $g_script_login_cookie, $g_cache_current_user_id;
$t_user_id = user_get_id_by_name( $p_username );
//patch start
//create users if not exists in the mantis DB but exits in the LDAP
if ( false === $t_user_id ) {
$t_login_method = config_get( 'login_method' );
if ( LDAP == $t_login_method && ldap_authenticate_by_username( $p_username, $p_password ) ) {
$t_auto_create = true;
}
if ( $t_auto_create ) {
$t_cookie_string = user_create( $p_username, md5( $p_password ) );
if ( false === $t_cookie_string )
return false;
$t_user_id = user_get_id_by_name( $p_username );
if( false === $t_user_id ) {
return false;
}
} else {
return false;
}
}
// if( false === $t_user_id ) {
// return false;
// }
//patch end
$t_user = user_get_row( $t_user_id );
