The "Oracle Siebel mobile web client" is required for connectivity with the CA Identity Manager (IM) as IM uses the "Siebel COM Data Control object" to connect to Siebel server and the Siebel Client provides all the required dll's to enable that connectivity (fore example, sstchca.dll - SiebelDataControl.SiebelDataControl.1).
