Retrieve lists of active directory users and display them in WordPress.
The best place to seek support is in the official WordPress support forums. If you don't get an answer there, you can try posting a comment on the official plugin page. Finally, you can hit me up on Twitter if you want me to take a look at something.
Yes. It can be activated normally on each individual site or it can be network-activated.
Yes. However, at this time, it is not optimized for a multi-network environment (without a set of functions that are currently unavailable to the public, as they are still under development separately from this plugin). Therefore, it will function as any other multisite-compatible plugin would function.
You should be able to, though it will make the plugin potentially even more incompatible with the Active Directory Integration plugin.
Yes, that is part of the core functionality of this plugin. You can easily filter the list of retrieved users with a specific AD group.
Not at this time. You can only provide one group at a time to filter the results.
Yes, you can provide a username (samaccountname or userPrincipalName) to retrieve and display a single user from active directory.
Documentation for the output builder can be found on the official plugin page. The same documentation can be found by clicking the "More info" link under the output builder field on the plugin's options page.
Following is a list of standard Active Directory fields of which I am aware (I used a list from a company called Computer Performance to compile this list):
That most likely means that too much information was retrieved and formatted at once by the plugin. Try retrieving/displaying fewer fields and/or filtering the list of users with a specific Active Directory group to see if that solves the issue. I have not yet implemented pagination in this plugin, so there is currently no way to limit the number of users it attempts to retrieve and display at once.
Unfortunately, there is a documented issue with PHP that it doesn't allow "paging" of query results. Therefore, it will only retrieve as many users as your Active Directory is configured to allow on a single "page" (appears to be 1500 by default).
