Hello,

 

I would like to run an Active Directory server on Docker, using either OpenLDAP or FreeIPA, to authenticate SMB shares and a few other Docker containers.

 

My goal is to use SMB with AD, so that users can authenticate via LDAP. However, when I go to SMB Settings > Active Directory Settings and attempt to join the AD domain, it tries for a few seconds and then fails.

 

I've also noticed that after every attempt to join the AD domain, all Docker containers restart. If the attempt is made while the containers are down, the connection will always fail.

 

Does anyone know why attempting to join the AD causes all Docker containers to restart? Has anyone implemented a similar setup and can provide some guidance?

 

root@Tower:~# docker ps
CONTAINER ID   IMAGE             COMMAND                  CREATED          STATUS                  PORTS                                                                          NAMES

I'm curious about doing this myself. Did you have any luck with it?

From an old post, it seems that dockers and VMs cannot run when the array is down. I'm not sure why but when SMB attempts to join an Active Directory, it causes the array to go down.

I haven't found a solution for this. It looks like in order to have an AD server and use it for SMB it needs to run as a plugin. However, I haven't found such a plugin and I don't know how to create one from a docker.
