Import and authenticate users from a particular group in Active Directory

Issue

Instead of importing and authenticating all users from Microsoft Active Directory (AD), I would like to only import and authenticate users from a particular group in AD.

In the Authentication Search Filter, specify the filter like this:

(&(objectCategory=person)(mail=@email_address@)(memberOf=cn=$Group_name,dc=mydomain,dc=com))

For multiple groups, the filter is like this:

(&(objectCategory=person)(|(memberOf=cn=$Group1_name,dc=mydomain,dc=com)(memberOf=cn=$Group2_name,dc=mydomain,dc=com)))

In the Groups > Import Search Filter, specify the filter like this:

(&(objectClass=person)(memberOf=cn=$Group_name,dc=mydomain,dc=com))

For multiple groups, change the search filter like this:

(&(objectClass=person)(|(memberOf=cn=$Group1_name,dc=mydomain,dc=com)(memberOf=cn=$Group2_name,dc=mydomain,dc=com)))

"$Group_name", "$Group1_name", "$Group2_name", should be changed to the group name in AD.
If the group name contains a special character (e.g. #), the special character should be escaped with "\\" in the Authentication Search Filter like this:
```
(&(sAMAccountName=@screen_name@)(|(memberOf=cn=\\#group1,ou=groupTest,dc=mydomain,dc=com)(memberOf=cn=\\#group2,ou=groupTest,dc=mydomain,dc=com)))
```
When clicking 'Test LDAP Users', only users with defined security group/s will be listed.
Wildcards are not supported for memberof attributes. Details can be found here.
