userCreate - PAM/Sudo Issue

Hello everyone,

I'm facing an Issue with spinning up the rstudio-workbench helm chart when deploying it with the Option userCreate = true . The creation of the local user goes through but the when it come to changing the password I see an error in the logs when spinning up the pod:

+ '[' -z rstudio ']'
+ useradd -m -s /bin/bash -N -u 10000 rstudio
+ echo rstudio:rstudio
+ sudo chpasswd
sudo: unable to send audit message
sudo: pam_open_session: System error
sudo: policy plugin failed session initialization
+ deactivate
+ echo '== Exiting =='
+ rstudio-server stop

Plattform: Openshift 4.10.22

UDPATE 1:

I was able to change the password of the local "rstudio" user with usermod --password rstudio rstudio but still cant login via the web gui.

Error: Incorrect or invalid username/password

UDPATE 2:

Testing the pam login with /usr/lib/rstudio-server/bin/pamtester --verbose rstudio rstudio authenticate reveals the follwing:

pamtester: invoking pam_start(rstudio, rstudio, ...)
pamtester: performing operation - authenticate
Password: 
pamtester: System error

Start with the Helm chart's userCreate=true startup path and the pod log around useradd, sudo chpasswd, and PAM session initialization; reproduce the authentication failure with the mentioned pamtester command. Done means the local rstudio user is created successfully and can log in through the web GUI on OpenShift.
