PAM Authentification is not working

[moritzxt]

Bug description

After installation of Jupyterhub with Anaconda configuring it and running Jupyterhub as a service on Rocky Linux 8.7 I can open up the login page of the jupyterhub, the service is running. When I try to login, there is an error displaying "Invalid Username or Password". For authentification I am using the default PAM Authentifacator.

Expected behaviour

Login successfully and start the Jupyterlab of the User

Actual behaviour

I can't login, with any useraccount. The error which I got with journalctl jupyterhub is:
PAM unable to dlopen(/usr/lib64/security/pam_unix.so): /lib64/libk5crypto.so.3: undefined symbol: EVP_KDF_ctrl, version OPENSSL_1_1_1b

How to reproduce

1.Set up Jupyterhub with recent openssl on your system
2. Configure it with PAM autehntification
3. Try to login
4. See error

I found a solution for the problem here https://bugzilla.redhat.com/show_bug.cgi?id=1829790
I deleted /miniconda/envs/hub/lib/libcrypto.so.1.1 now it seems to work
