If You should try to login using what you believe is a valid username and password. If you view the source of the page if will be displayed in a more readable format:

If no login attempt has been made it will show you only which plugins managed it managed to find in Rogo. You should check that all that you expect are listed, and that they are in the order you expect.

If there are any failures at this stage it means that the $authentication setting in the config/config.inc.php is incorrect.

If that is the case try logging in.

you may find the information to be more readable:

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

Code Block
languagephp
  [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

Code Block
languagephp
[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

Code Block
languagephp
  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:

Code Block
languagephp
titleLDAP started authenticating
string(33) "authObj(LDAP:ldap)[5:0]:: Authing"

Problems in the LDAP plugin

MessageExplanation
Check 1 blank entriesA 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 searchThe 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 providedThe 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 very customized Rogo setup.

LDAP Record found but no local accountYou may need to create an account for the user in Rogo
setting is set to disable lookupThe user will not have an account created automatically, you will need to manually create their Rogo account
