Hello, On this page: http://www.gluu.org/docs/articles/mod-auth-oidc/centos-installation/ I think that the following line should be added to the "mod_auth_openidc.conf" file: Listen 44443 Inside of the "mod_auth_openidc.conf" file, I think it should be added to allow the server to listen for traffic on the needed port. The instructions did not work for me until I added this. The file contents should be: LoadModule auth_openidc_module modules/mod_auth_openidc.so Listen 44443 Adrian
