SSO SAML Blank Page error

Original Question or Issue:

  • 'Log in with SSO' is redirecting to a blank page while trying to log into the FileCloud Server from the web interface

Environment:

  • Product - FileCloud Server/Online
  • Version - 23.252
  • Platform - Linux

Steps to Reproduce:

  • Configure SSO (SAML) from the Admin Portal
  • Configure the IdP  (Azure)
  • Configure the SP (FileCloud)
  • Try logging into the Web Portal using the 'Log in with SSO' button

Error or Log Message:

  • After pressing 'Log in with SSO' button, a blank white screen appears


    FileCloud Server Logs (SAML-related errors):
  • YYYY-MM-DD 11:47:10.353242 DEBUG: [1544578][17612380302815] SAML Authentication Failed SAML Authentication Failed
  • YYYY-MM-DD 11:52:21.036465 DEBUG: [1545441][17612383410192] getSamlConfig: saml cert directory not found at /var/www/html/resources/samlcerts/default/

Defect or Enhancement Number:

Cause:

  • The IdP (Azure) was looking for this specific parameter inside the FileCloud SSO settings:
    http://schemas.xmlsoap.org/ws/2005/05/identity/claims/mail

  • After reviewing, the FileCloud Server SSO settings had been configured with this parameter:
    http://schemas.xmlsoap.org/ws/2005/05/identity/claims/emailaddress

Resolution or Workaround:

  • After fixing the incorrect parameter '/emailaddress' to instead be '/mail' in the Admin Portal, SSO began working as expected
