login flow: delegatedAuthentication step transition on resume event

[Pablo Vidaurri]

Any idea what triggers the resume event while performing delegated authentication? It seems this is trying to insert a TST into the db which already exist and is causing a PK constraint violation then redirects to error page. It is happening multiple times  a day for some delegated users.

Login flow:

- delegatedAuthentication>
-- [TRANS] success -> createTicketGrantingTicket>
-- [TRANS] select -> delegatedAuthenticationSelectCredential>
-- [TRANS] generate -> initialAuthenticationRequestValidationCheck>
-- [TRANS] successWithWarnings -> showAuthenticationWarningMessages>
-- [TRANS] resume -> createTicketGrantingTicket>
-- [TRANS] authenticationFailure -> checkDelegatedAuthnFailureDecision>
-- [TRANS] stop -> stopWebflow>
-- [TRANS] warn -> warn>
-- [TRANS] generateServiceTicket -> generateServiceTicket>
