When using non standard port (8081) Post authentication redirect does not use specified PORT

• Our intention is to run this on a non standard port
• Using the "port deployment" instructions from the readme
• I am able to put the container up successfully and access the authentication page via http://auth.sso.llng:8081/ (changed example.com to sso.llng)
• I believe the login form is working correctly as if I enter incorrect login information I get a failed login as expected
• When attempting to login with the correct details the post login redirect does not contain the port number (8081) redirects to: http://auth.sso.llng/
• Looking at the network tab I can see the post does a 302 redirect to this location without the port number.

If we can be pointed to where this redirect is happening we can have a look to see if we can resolve, unless there is anything else we should check.

You need to configure the portal parameter to this value: http://auth.sso.llng:8081/

Thanks for the quick response.

Where is this parameter set?

[coudot]

It is not set by the Dockerfile, you must access to Manager or use lemonldap-ng-cli

We could indeed add an environment variable to declare which public port will be used to access the container

Great it worked thank you! These are the commands that fixed it.

/usr/share/lemonldap-ng/bin/lemonldap-ng-cli -yes 1 set domain sso.llng
/usr/share/lemonldap-ng/bin/lemonldap-ng-cli -yes 1 set portal http://auth.sso.llng:8081/

• Are there any compose variables that are redundant?
• Are there any other common problems the cli fixes?
• Would you like a pr on the readme with these instructions?

The domain should have been set by SSODOMAIN env

For the port, we need to not mix the internal port of the container which the external port (they can be different in port mapping). That's why we may need to introduce a new env var to manage this.
