Have you recently upgraded your application? It looks like you have an older version of the SSO module that uses the deprecated execute method in Core. The solution is to download a newer version of the SSO module from the Marketplace, but do remember to delete the old required jar files from the userlib first as you could have some conflicts otherwise.

Hope this helps.
