The PingFederate WS-Trust STS is designed to interoperate with many different web-service environments that support varying standards. PingFederate supports multiple versions of SOAP and WS-Trust specifications, and can freely operate with any combinations of these standards simultaneously.

PingFederate supports namespace aliasing to eliminate common trailing-slash inconsistencies for WS-Trust 1.3. (The server does not support namespace aliasing for WS-Trust 2005.)

Supported SOAP/WS-Trust versions and corresponding namespaces are listed in following table:
