Original GitHub issue: https://github.com/maziggy/bambuddy/issues/794

Originally assigned to: @maziggy on GitHub.

Problem or Use Case

Would love a way to allow for LDAP auth for users to auth to Bambuddy, rather than local accounts

Proposed Solution

LDAP auth, coming from Active Directory - SAML with EntraID would be even better, but that could be harder.
User groups based on AD/ Entra Groups (so, something like, Bambuddy_Operator, Bambuddy_Admin, Bambuddy_Viewer).

Alternatives Considered

Not really any workarounds for it.

Quick note on scope: We'll be implementing pure LDAP bind authentication. SAML, OIDC, and Entra ID/Azure AD integrations are out of scope — we want to keep this clean and dependency-light.

Before we start building, we'd love community input on a few design questions:

Coexistence with local accounts

Should LDAP users exist alongside local accounts? (e.g., local admin as fallback when LDAP server is unreachable)
Or should enabling LDAP replace local auth entirely?

Group-to-role mapping

Should we map LDAP groups to Bambuddy's existing roles (Admin, Operator, Viewer)?
If so, should this be configurable? (e.g., "LDAP group PrintFarm_Admins → Bambuddy Admin")
Or should all LDAP users get the same default role, with admins promoting manually?

User provisioning

Auto-create Bambuddy user on first successful LDAP login (just-in-time provisioning)?
Or require an admin to pre-register allowed LDAP usernames?

Configuration

LDAP server URL, bind DN, search base, group filter — anything else you'd need for your setup?
Does anyone need LDAPS (LDAP over TLS) or StartTLS?

Please share your thoughts and upvote the options that work best for your environment!

Hi Maziggy,

I would think, LDAP should exist with local accounts - at least just the admin account, so if the server isn't available the admin can fix it easier.
Yes, role mapping would be great. And yes, configurable options for the name of the AD based groups please. Different places have different requirements for naming of things in AD. If the roles are too hard, admins can change the user afterwards, that's ok too, but having it automated based on the AD group would be great.
User provisioning, perhaps leave that up to the admin to decide. I would rather add people who need access, than have it be a free for all.
Those LDAP options should be fine, maybe support LDAPS if you have time? Probably should moving forward.
Thanks for all the amazing work you've done with this project!
