#2

Is it reproducible?

The user selfservice doesn’t get access to the database selfservice with the password stored /etc/self-service-db.secret.

Any hints in syslog or postgres log?


#3

yes, always.

To fix the database password run:

PASSWORD="$(cat /etc/self-service-db.secret)"
su - postgres -c "echo \"ALTER ROLE selfservice WITH ENCRYPTED PASSWORD '$PASSWORD';\" | psql"
systemctl restart univention-management-console-server.service

What server role is this installed on?

ucr get server/role

Was the package univention-self-service-passwordreset-umc properly installed?

dpkg -l univention-self-service-passwordreset-umc

That’s weird… the installation procedure of the package should have created the DB user…

How was the self-service app installed? Directly from DVD, from the app center or manually via the package manager?

If you completely uninstall the package and reinstall it, the DB user will be created:

apt-get purge univention-self-service-passwordreset-umc
univention-install univention-self-service univention-self-service-master

I installed it via AppCenter.After purge & install the only thing changed is the user’s appearance of selfservice on psql roles
