Unsolved Connecting Synology NAS to Cloudron LDAP fails

[imc67]

Hi, I really would like to connect our Synology NAS (DSM 7.1.1) to our Cloudron LDAP so our Cloudron users can login to the NAS with the same credentials. That saves a lot of time and issues with user management.

After some trial and error I got to a point where I can't solve the issue, who knows how to continue?

In Synology DSM there is a wizard to start the connection:

Step 1: (server IP and DNS IP's)

Step 2: Enter needed info, got inspiration from the Cloudorn docs
BIND DN: cn=admin,ou=system,dc=cloudron
Password: set in LDAP Cloudron
BASE DN: ou=users,dc=cloudron

Step 3: check and join, first 3 checks succeeded but 4th one failed:

Without being able to debug this further, for a start, the filter seems wrong. The Cloudron provided user records would have the following objectClass attribute:

objectclass: [ 'user', 'inetorgperson', 'person' ]

so use one of those three entries there. Also Cloudron has no attribute uidNumber maybe using entryuuid works there though.
