Logoff from Pega does not redirect to SSO Logoff screen

SA-46194

Summary



After upgrading to Pega 7.21, Logoff from the Pega application does not redirect to the SSO Logoff screen and a blank window appears instead.


Error Messages



Not Applicable


Steps to Reproduce

  1. Upgrade from Pega 6.3 SP1 to Pega 7.2.
  2. Configure the LDAP Authentication.
  3. Log in to the Designer Studio.
  4. Click Logoff. The SSO provider's logoff screen does not appear and a blank screen appears which appears similar to Pega 6.3 SP1.


Root Cause



An issue in the custom application code or rules. The out-of-the-box META tag was removed from the Web-Session-Return HTML Stream rule which resulted in a blank Pega screen being displayed after logoff.


Resolution



Perform the following local-change:
  1. Set 'Log off redirection' as 'Show Log off Screen' in the Definition tab of the Application Definition rule.
  2. Create an 'unauthenticated' ruleset.
  3. Create an 'unauthenticated' access group to be used by unauthenticated requestors.
  4. Map the 'unauthenticated' ruleset as Production ruleset in the Advanced tab of the 'unauthenticated' access group.
  5. Map the 'unauthenticated' access group (created in Step 2) to the Browser RequestorType.
  6. Save the Web-Session-Return HTML Stream to the 'unauthenticated' ruleset.
  7. The below out-of-the-box META tag in Web-Session-Return HTML Stream redirects to login screen.
<META http-equiv="refresh" content="0;URL=<pega:reference name="$save(servURL)" />">

Include this line to update the URL and point to the third party Logff URL.

For example:

<META http-equiv="refresh" content="0;URL=https://smlogin/your_SSOsolution/ssologout/Logout.html" />
