Search BOM in PDMLInk from WPA is not working with SSO

Hi,

After configuring SSO on Windchill with shibboleth as Service provider, we are not able to search BOM in PDMLink from WPA. When we perform the BOM search from WPA, we get below error in UI. 

Windchill PDMLink caused an unexpected error - White Spaces are required between publicID and systemID
