Hi everyone, I’m encountering a problem specific to my program flow using the azuread oauthenticator.
I need to create an aad system user for everyone that logs in and authenticates through my organisation’s Azure AD.
For that there is a debian package called aadlogin. Basically using the function aaduseradd I can create a system user that is registered remote with the AD.
I think that that function is not ideal at the moment, as it can take up to half an hour to add a user this way.
Currently, I have a pre_spawn_hook that calls a shell script that makes the aad user, mounts a file share, and creates symlinks.
Because the aaduseradd function takes so long, JupyterHub locks up inside the pre_spawn_hook.
Basically, the hub doesn’t work while inside that shell script.
I’ve tried making the pre_spawn_hook a coroutine, to no avail.
How can I make sure the hub isn’t interrupted while spawning a user?
I’ve found out the reason for the command aaduseradd being so slow; instead of using symlinked directories like in /etc/skel it downloads the full data (260MB -> 11GB). This can take a long time.
If I can fix that I suspect the problem will be of a smaller magnitude, but I’d still like to know how I can make the pre_spawn_hook non-blocking.
