How to authenticate via AD to non-domain server

zachary715

Ubuntu 18.04 on VMware. Would consider joining to domain if it's the easier option. Just didn't know if it was something basic I was missing.

I know that joining CentOS and Fedora to a domain is quick and easy, but I've not attempted it with Ubuntu.

Ubuntu is easy too in basically the same way.

Can you use RADIUS? Was able to get our firewalls to authenticate VPN users against Microsoft's RADIUS implementation and validate against specific security groups in AD.

Interesting the use of "Log On to", I am not sure you can without joining the domain or having a DNS entry.

It has a DNS entry, but still doesn't work. I'll just join to domain and see how that goes.

Don't currently have RADIUS setup, so this seems to be the long way around the issue. Thanks for the suggestion.

This is definitely because it's not domain joined

18.04 changes quite a bit of stuff. Typically easy though

Just joined to domain and still having same issue. I even limited my own account to just bookstack and it wouldn't let me log in. Error says "These credentials do not match our records". As soon as I remove Log On To restrictions, these accounts can sign in.

Verified domain join by running id DOMAIN\\user and ensured I was getting user properties back.

Followed these steps to join to domain... https://www.server-world.info/en/note?os=Ubuntu_18.04&p=realmd

Server gets IP from DHCP, there's a new computer entry in AD further verifying it successfully joined domain, and I also verified the DNS entry for the server. Not having passed AD authentication before for a scenario like this, not sure if this is typical or some issue with bookstack authentication specifically.

@zachary715 post your .env file

@zachary715 Try using your hostname without the port specified for LDAP_SERVER=

I followed the thread you and @dbeato were discussing setting it up, so I'm assuming you have it running and authenticating. If you specify machines in AD via Log On To, can you still have them log in?

Yes I can. I'm also running it on 16.04 though

Same results...

@zachary715 Everything looks correct to me in your .env file. Not sure

zachary715

Yeah I've gone back to Ubuntu's documentation and even added some of the things for AD join that the other tutorial didn't mention, and still no luck. What a pain. I may spin up a 16.04 server and see if I can get that to work.

@wirestyle22 If you have time and can make a clone of your bookstack install and upgrade it to 18.04 and test, that might be helpful as well.

wirestyle22

@zachary715 that may not be a graceful upgrade. I haven't compared. I know a lot changed with 18.04. I'd be willing to do it but it's dependent on whether or not my vxrail servers explode again or not. Nothing like multiple millions of dollars worth of hardware having issues to keep you up at night

Haha no worries then. I'm going to install it on 16.04 and see if it works. If it does, then I'll upgrade to 18.04 and see what happens.
