File shares on domain controller


We are in Univention planning and testing stage. We currently plan for 3 servers:

  • Primary DC
  • Additional DC
  • File Server on domain member

We also need a backup file server but don’t have a spare hardware. Are there any disadvantages of using domain controller as a file server too?

Samba project doesn’t recommend that (covered in

What about Univention team? Are we going to have problems if we decide to do that? Maybe there’s no problem at all and we can put main file shares on Primary DC and backup file shares on Additional DC and use 3rd server for opnsense?



Anyone wants to share, please ?

no problems for me with fileshares on DC - have some single server installs - everything works - i think it depends of how much users are there regarding authentications (AD authentication)
