SecuritySuite - SuiteCRM and CE Teams

I'm assuming that the $rel_name is "SecurityGroups". I gave this a good try by looking through Sugar's code, but unfortunately you can only get the securitygroups table. The securitygroups_users table just isn't accessible with Sugar's framework. So the only way to do this is to do a direct SQL query and pass the user ID and the group ID. Make sure to also check for deleted = 0.

I am using now as following :

        $rel_name = $this->getLinkName ( $user->module_dir, 'SecurityGroups' );
        if ($rel_name) {
            $user->load_relationship ( $rel_name );
            $userSecurityGroups = $user->$rel_name->getBeans ();

            if (! empty ( $userSecurityGroups )) {
                foreach ( $userSecurityGroups as $userSecurityGroupId => $userSecurityGroup ) {
                    //you can load any table 
                    $securityGroupUserRelationshipRows = $user->retrieve_relationships ( "securitygroups_users", array (
                            "securitygroup_id" => $userSecurityGroupId,
                            "user_id" => $user->id,
                            "noninheritable" => 0 
                    ), "{COLUMN_OF_SECURITYGROUP_USERS}" );
                                 }
                          }
                   }
