Error on Portal Logon Page

100 Views

Hi Experts,

We are getting exception while calling the Portal URL.

Recently, we changed the password policy and made some customizations on the com.sap.portal.runtime.logon.par file.

After that when I tried to access the Logon page, it gave an exception.

I even replaced the customized logon par file with the original one but it did not help.

Please note that I deployed the logon par file with the same name, so I did not have to make any changes in the authschemes.xml file.

So ideally when I replaced the customized PAR file with the original one, it should have worked out.

Can it be because of some UME property "Password Policy change" or something like that which has been changed by our Basis team in the Config tool and which is creating issues now.

Is there any connection between the UME property and the Portal Logon page? I know that UME comes into picture once the user clicks on Login button after entering the login credentials but does it also come in picture at the portal logon page call?

We are not able to trace out the root cause as both Password Policy Change and deployment of PAR was done parallely due to which we are confused about the cause of the issue.

Please find below the trace against the exception ID:
