Is it possible to get additional fields from AD, such as position, department and save them to the user's profile?
Topic on Extension talk:LDAPUserInfo/Flow
One can actually fetch additonal data and map them to user preferences. Unfortunately there may be no fields for position and department in the default MediaWiki user preferences.
See "properties.gender": "gender"
part in the example. this will set the MediaWiki user preference "gender" to the value of the "gender" attribute contained in the LDAP user info.
