Hi Experts,

Is there any webservice/Bapi available for this purpose? if not how we can achieve this?
Thanks in advance

Hi,
I don't think there is any web service to just check authentication but the work around is simple :
Call any web service which just display some information (for example call STFC_CONNECTION function module as a web service).
As you need to authenticate to call the web service, send the user/password.
If you get the release information, the user/password is OK.
If you get HTTP 401 error, the user/password is KO.
Of course the user needs the authorisation to execute the STFC_CONNECTION function module.
Regards,
Olivier
