This document is a work in progress.

If you cannot login to Rogo try enabling authentication debugging via the display_auth_debug setting in config/config.inc.php

$display_auth_debug = true;

This will add extra information to the login page.

You should try to login using what you believe is a valid username and password. If you view the source of the page you may find the information to be more readable:

Username of myusername tries to login. The username does not exist

}

In the example above a username that does not exist in any of the authentication methods was used.

What to look for

That authentication has some configuration information

  [0]=>
  string(32) "Loaded Config for authentication"

If this is not present your config.inc.php did not contain an authentication setting

That Rogo received the login details

[1]=>
  string(171) "Standard form data found - Storing in object array (
  'std' => 
  stdClass::__set_state(array(
     'username' => 'myusername',
     'password' => '***HIDDEN***',
  )),
)"

If this is not present and you entered a username and password, this data was stripped before it got to Rogo

Examine what happened in each authentication method

  string(23) "Starting authentication"

All of the information below this point shows what happened against each of your setup authentication methods.

For every authentication plugin you configured there should be a line similar to:

LDAP started authenticating

string(33) "authObj(LDAP:ldap)[5:0]:: Authing"

Problems in the LDAP plugin

This plugin requires that the PHP ldap module is installed on your server.

Message	Explanation
Check 1 blank entries	A username and/or password was not sent
Could not bind to ldap server	Either the server specified in 'ldap_server' is not available or the username 'ldap_bind_rdn' or password 'ldap_bind_password' settings are incorrect
LDAP Server Unavailable: unable to search	The syntax of 'ldap_search_dn' or 'ldap_user_prefix' is likely to be incorrect
No LDAP account found!	A username could not be found in the LDAP tree specified in 'ldap_search_dn' where the username is stored in the value 'ldap_user_prefix'.
Incorrect password provided	The password provided does not match the one recorded in LDAP for the username
Check 2 record number not = 1 no user or multiple user found in lookup	More than one record matched the username in the internal Rogo user table. Check the values of: 'table' - The name of the table Rogo stores users. (Default: 'users') 'username_col' - The name of the database column that the username is stored (Default: 'username') 'id_col' - The name of the database column that stores the internal Rogo id of the user (Default: 'id') It is unsafe to modify these from the defaults unless you have a customized Rogo setup and know what you are doing..
LDAP Record found but no local account	You may need to create an account for the user in Rogo
setting is set to disable lookup	The user will not have an account created automatically, you will need to manually create their Rogo account
