* getLdapGroups queries LDAP and returns a slice describing the set of groups the authenticated user is a member of.

* The search query is constructed according to cfg.GroupFilter, and run in context of cfg.GroupDN.
* Groups will be resolved from the query results by following the attribute defined in cfg.GroupAttr.
*
* cfg.GroupFilter is a go template and is compiled with the following context: [UserDN, Username]
* UserDN - The DN of the authenticated user
* Username - The Username of the authenticated user
*
* Example:
* cfg.GroupFilter = "(&(objectClass=group)(member:1.2.840.113556.1.4.1941:={{.UserDN}}))"
* cfg.GroupDN = "OU=Groups,DC=myorg,DC=com"
* cfg.GroupAttr = "cn"
*
* NOTE - If cfg.GroupFilter is empty, no query is performed and an empty result slice is returned.
