Error in Shibboleth login from mobile devices

[Aseem Keskar]

Hello Team,

We have implemented Shibboleth SSO login in our mobile application. Our mobile application has been built on IONIC3.

We are frequently facing issue on Shibboleth login for mobile devices where sometime it redirects to error (find the attached error screenshots) and sometime it works fine without any error. Shibboleth login for mobile device is not working consistently.

We are facing this issue in iOS device more frequently (this error appears 1 or 2 times out of 4-5 login attempts). For Android device, it is not coming so frequently like iOS (for Android error appears 1 or 2 times out of 14-15 login attempts).

We found the following error in the log file from IdP server.

[net.shibboleth.ext.spring.error.ExtendedMappingExceptionResolver:136] - Resolved [org.springframework.webflow.execution.repository.NoSuchFlowExecutionException: No flow execution could be found with key 'e1s2' -- perhaps this executing flow has ended or expired? This could happen if your users are relying on browser history (typically via the back button) that references ended flows.] to ModelAndView: reference to view with name 'error'. 

Kindly help us to find root cause of this error and provide some solution for the same?

Thanks and regards,
Aseem Keskar
