Clean up groups request to use filters

[lowinger42]

I have tried to activate Librenms LDAP support against lldap.
The user bind is successful, then Librenms tries to verify group membership to grant permissions (admin, global_read, normal).
There are three ways to "find group members by"

• Username
• Full DN (using prefix and suffix)
• DN Search (search using uid attribute)

None of these works. Debug log when using Username:

lldap_1 | 2022-01-23T22:39:26.440636Z DEBUG lldap::infra::ldap_handler: Received search request: LdapSearchRequest { base: "ou=groups,dc=int,dc=abundo,dc=se", scope: Subtree, aliases: Never, sizelimit: 0, timelimit: 0, typesonly: false, filter: And([Equality("cn", "librenms_admin"), Equality("uniqueMember", "")]), attrs: [] }

@lowinger42 can you try getting Librenms to work with the latest docker image?
