I assume you mean "I only want to allow users of this group to access
some resource"

I think it would be best to use several LDAP operations rather than
trying to do everything in one go. For example:
1) Search for user:
base: ou=user,dc=example,dc=com
filter: (&(objectclass=account)(uid=<username>))
If the user exists, note the DN of the entry found.
2) Authenticate user:
Bind as the user DN using the user-supplied password
If this fails, deny access.
3) Re-bind as a system user (or anon if that has enough access)
4) Check authorisation:
Search base: CN=internal,OU=group,DC=example,DC=com
Search scope: base
Filter: (member=<user DN>)
Return attributes: cn
If this returns an entry then the user is in the authorisation
group and should be allowed to use the resource. Otherwise,
deny access.
