Is this the first time you’ve seen this error? (Yes / No):

When did this problem seem to first start?
after installing the "SSO & SAML authentication" application

No
Summary of the issue you are facing:
After installing and configuring the “SSO & SAML authentication” application (user_SAML) and enabling “Allow the use of multiple user backends (e.g. LDAP)”, when accessing the login - the page URI is “/apps/user_saml/saml/selectUserBackEnd?redirectUrl=” - the login method selection is not displayed. Only the page with the theme set in the “Themming” application is displayed.
There are no error messages in the log, Nextcloud is running from the official docker container with the tag 31-apache. This is a new clean “installation” of the mentioned version. “Allow the use of multiple user backends (e.g. LDAP)” is enabled in the user_SAML application as I mentioned. Thanks for the advice.
