How-To: Use a regular expression to create an LDAP Group filter.

Goal

Filter LDAP group results using a regular expression with the group filters textarea for my External Authenticator (LDAP).

Given the below groups, filter out anything that does not start with DATAMEER-TEST.

• DATAMEER-TEST-ANALYST
• DATAMEER-TEST-BA
• DATAMEER-TEST-DATASCIENTISTS
• DATAMEER-PROD-ADMINS

Unfortunately, a simple wildcard DATAMEER-TEST-* does not work and no groups pass this filter.

In the event that a simplified regex does not work, it's possible to use a strict regex.  Navigate to the Group Filters -> Include These Groups section of External Authenticator settings.

^\w*DATAMEER\w*[-]\w*TEST\w*[-][A-Za-z]* will achieve the described example. It covers all groups with names that start with DATAMEER-TEST- and then have any other letter A-Z or a-z.
