It seems the problem is casued by CAS failed to verify the "execution" value.
I am having this problem when there are multiple nodes of CAS and I have resolved this problem by setting *webflow.encryption.key* and *webflow.signing.key* in cas.properties. According to CAS documentation, If keys are left undefined, on startup CAS will notice that no keys are defined and it will appropriately generate keys for you automatically. https://apereo.github.io/cas/4.2.x/installation/Webflow-Customization.html#webflow-session Kartik Mehta於 2016年12月12日星期一 UTC+8下午9時46分52秒寫道： > > Basic stuff, but I hope the value of tgc.signing.key > and tgc.encryption.key are set to the same value in all your CAS nodes in > the cluster ? > > regards, > Kartik > > On Mon, Dec 12, 2016 at 10:24 AM, Colin Wilkinson <[email protected] > <javascript:>> wrote: > >> We are getting the same issue in production, did you manage to solve this >> >> On Wednesday, 23 November 2016 17:18:34 UTC+11, liu chenghai wrote: >>> >>> I have the same problem and don't resolve >>> >> -- >> - CAS gitter chatroom: https://gitter.im/apereo/cas >> - CAS mailing list guidelines: >> https://apereo.github.io/cas/Mailing-Lists.html >> - CAS documentation website: https://apereo.github.io/cas >> - CAS project website: https://github.com/apereo/cas >> --- >> You received this message because you are subscribed to the Google Groups >> "CAS Community" group. >> To unsubscribe from this group and stop receiving emails from it, send an >> email to [email protected] <javascript:>. >> To view this discussion on the web visit >> https://groups.google.com/a/apereo.org/d/msgid/cas-user/1076d175-4bb0-43e5-b1bb-0e88701f7a34%40apereo.org >> >> <https://groups.google.com/a/apereo.org/d/msgid/cas-user/1076d175-4bb0-43e5-b1bb-0e88701f7a34%40apereo.org?utm_medium=email&utm_source=footer> >> . >> > > -- - Website: https://apereo.github.io/cas - Gitter Chatroom: https://gitter.im/apereo/cas - List Guidelines: https://goo.gl/1VRrw7 - Contributions: https://goo.gl/mh7qDG --- You received this message because you are subscribed to the Google Groups "CAS Community" group.
