A ‘User Email is required’ error page appears after login¶
This error appears normally during the first login just after installing the ioChem-BD software.
In this case, the user gets the following error message:
User Email is required Your SSO system is not configured properly to release user email info
The error is due to a misconfiguration in the machine that runs ioChem-BD software. In this case, the Central Authentication Service (CAS) can’t find its own domain because it’s not defined in /etc/hosts file. This results in missing user profile information right after authentication.
Steps to fix it¶
The sysadmin of the server running ioChem-BD software must append a line inside /etc/hosts file.
This line must set loopback IP of the machine (127.0.0.1) to the host.hostname parameter defined during installation.
As an example, if ioChem-BD is running on test.iochem-bd.org, the line to add inside /etc/hosts should be the following
After editing this file, the error will disappear just by reloading the login page or log in again.
