What is the issue you are experiencing?

When using LDAP as authentication method, the following error is given in the log:

ImportError: libldap_r-2.4.so.2: cannot open shared object file: No such file or directory File "/opt/pysetup/.venv/lib/python3.10/site-packages/starlette/middleware/gzip.py", line 24, in __call__ await responder(scope, receive, send) File "/opt/pysetup/.venv/lib/python3.10/site-packages/starlette/middleware/gzip.py", line 43, in __call__ await self.app(scope, receive, self.send_with_gzip) File "/opt/pysetup/.venv/lib/python3.10/site-packages/starlette/middleware/exceptions.py", line 75, in __call__ raise exc File "/opt/pysetup/.venv/lib/python3.10/site-packages/starlette/middleware/exceptions.py", line 64, in __call__ await self.app(scope, receive, sender) File "/opt/pysetup/.venv/lib/python3.10/site-packages/fastapi/middleware/asyncexitstack.py", line 21, in __call__ raise e File "/opt/pysetup/.venv/lib/python3.10/site-packages/fastapi/middleware/asyncexitstack.py", line 18, in __call__ await self.app(scope, receive, send) File "/opt/pysetup/.venv/lib/python3.10/site-packages/starlette/routing.py", line 680, in __call__ await route.handle(scope, receive, send) File "/opt/pysetup/.venv/lib/python3.10/site-packages/starlette/routing.py", line 275, in handle await self.app(scope, receive, send) File "/opt/pysetup/.venv/lib/python3.10/site-packages/starlette/routing.py", line 65, in app response = await func(request) File "/opt/pysetup/.venv/lib/python3.10/site-packages/fastapi/routing.py", line 231, in app raw_response = await run_endpoint_function( File "/opt/pysetup/.venv/lib/python3.10/site-packages/fastapi/routing.py", line 162, in run_endpoint_function return await run_in_threadpool(dependant.call, **values) File "/opt/pysetup/.venv/lib/python3.10/site-packages/starlette/concurrency.py", line 41, in run_in_threadpool return await anyio.to_thread.run_sync(func, *args) File "/opt/pysetup/.venv/lib/python3.10/site-packages/anyio/to_thread.py", line 31, in run_sync return await get_asynclib().run_sync_in_worker_thread( File "/opt/pysetup/.venv/lib/python3.10/site-packages/anyio/_backends/_asyncio.py", line 937, in run_sync_in_worker_thread return await future File "/opt/pysetup/.venv/lib/python3.10/site-packages/anyio/_backends/_asyncio.py", line 867, in run result = context.run(func, *args) File "/app/./mealie/routes/auth/auth.py", line 58, in get_token user = authenticate_user(session, email, password) # type: ignore File "/app/./mealie/core/security/security.py", line 120, in authenticate_user return user_from_ldap(db, email, password) File "/app/./mealie/core/security/security.py", line 51, in user_from_ldap import ldap File "/opt/pysetup/.venv/lib/python3.10/site-packages/ldap/__init__.py", line 34, in <module> import _ldap ImportError: libldap_r-2.4.so.2: cannot open shared object file: No such file or directory

Due to the error, LDAP authentication always leads to an error and makes it impossible to login.

The problem seems to be that the package libldap-2.4-2 is missing.

After installing the package using the following command, the issue is resolved:
apt-get update && apt-get install -y libldap-2.4-2

Unfortunately, due to additional bugs within the LDAP authentication, it is still not possible to login after the change. I will create a separate bug report for those, since they are code based.

Deployment

Docker (Linux)

Deployment Details

Docker install using a portainer stack on an unraid system.

Can confirm - seeing this on the latest beta release:

mealie-api | File "/app/./mealie/core/security/security.py", line 51, in user_from_ldap
mealie-api | import ldap
mealie-api | File "/opt/pysetup/.venv/lib/python3.10/site-packages/ldap/init.py", line 34, in
mealie-api | import _ldap
mealie-api | ImportError: libldap_r-2.4.so.2: cannot open shared object file: No such file or directory

Can also confirm I am seeing this issue.

Also seeing this (Docker on Ubuntu 22.04) and can't install libldap-2.4-2 - are there any known workarounds for this issue or should I move to 20.04 (my reading suggests it's supported on that version of Ubuntu)?
