I mean: if you use the naming from adLDAP, then you don't have to convert the options when initialising adLDAP, but just pass the options array directly.

So, instead of 
`$conf['auth']['auth_AD']['accountSuffix']`
 you put 
`$conf['auth']['auth_AD']['account_suffix']`
 in config.php

From the adLDAP docs:

* string account_suffix
* string base_dn
* array domain_controllers
* string admin_username
* string admin_password
* boolean real_primarygroup
* boolean use_ssl
* boolean use_tls
* boolean recursive_groups
* integer ad_port
* boolean sso
