Thanks all for all your valuable time and support..

Issue got fixed ...by replacing the Property (Path to Authscheme File (login.authschemes.definition.file): )in nwa/auth to standared value.

Path to Authscheme File (login.authschemes.definition.file):authschemes.xml as their a custom .xmal file was appearing.

[junwu]

i think you have to re-implement the custom logon screen

[Former Member]

Hi Jun,

What do you mean by Implementing the custom logon screen .
I am getting the following runtime error also a certificate error in IE browser. Kindly suggest..

[Former Member]

HI,

Post the error you are getting by searching exception ID in the log viewer.

How to see log viewer:

a) Create an iView of PAR type referring to standard par *.*....logviewer

b) Preview log viewer iview

c) search for the exception ID to see more details of the error

Hi,

Please refer the property Alias of the application for customizing logon page and reset to default value. reference link http://scn.sap.com/docs/DOC-27909

Kindly suggest.

Srinivasan V

[Former Member]

Hi Srini,
Thanks for your help but can u tell us which properties of the service should we check.below is the screen short .Kindly suggest what is missing.

[former_member246153]

Hi,

Did you find any property with the name login.authschemes.definition.file in that list , Please check what is the value given it and if it has any custom value restore it to default and Restart the Portal server and check...

Srinivasan V

[Former Member]

hi Srini,

           what has to be maintained in that  property "login.authschemes.definition.file" ?is it "authschemes.xml" for the std logon page to appear but their its maintained as "authscheme_RIP_SP9.xml"

Kindly suggest.

[former_member246153]

Hi,

Please refer the below link

http://help.sap.com/saphelp_nw73/helpdata/en/a2/03aa3d5acd40f082db65ee59c360b7/content.htm

In PropertySheet look for the property login.authschemes.definition.file.

Instead of applying custom value Restore the value to default.

Hope it will help.

Regards,

Srinivasan V

[Former Member]

Hi Srini,
       I want the standard logon portal only i don't want the custom logon page for now.

What entry should appear in this property "login.authschemes.definition.file" to retain the standard logon.

Regards,

Prajakta k

[former_member246153]

Hi,

Have you got that property login.authschemes.definition.file or authscheme.xml refrence ? if so double click on that property and try to edit that property. It will give you a popup where it has Restore Default button at the bottom.If you click this button it will automatically reset the Standard Authscheme.xml value.

Please take help from Basis if required

Hi,

Please refer the below link

hi srini,

       Yes we got that file authscheme.xml under the service "com.sap.security.core.ume.service "
   Also "login.authschemes.definition.file" with the value as "authschemes_RIP_SP9.xml" and when we edit its showing the same value in default.

even then should we try to restore default.

Thanks for your instant reply..

Hi,

Please check in NWA the portal logon page configuration. As you need standard logon page, please make sure you have standard WAR file configured for logon page.

[Former Member]

hi Ganga,
Following is the screen short of the nwa/auth log.what you want me to check here..I have highlighted the few of the points . In which i am unable to understand what should be the value of path of authscheme file if i want the std logon page.

Regards,
Prajakta k

[Former Member]

Hello Srini,
            The button is disable so we are not able to reset it to default.

and it gives same value in default .

regards,
Prajakta

[abdulbasit]

Did you try to change the value to "authschemes.xml" ?
