/*
 * 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.
 *
