User Synchronization between publish for SAML Authentication

[ankitg2807]

Hi,

I have configured SAML Authn Handler to enable login on website. We have 2 publish instances behind 2 dispatchers and a loadbalancer.

Encapsulated tokens are enabled on the 2 publish instances . When we login , user gets created on the publish instance serving the request but on refresh the request goes to 2nd publish instance and I get 404. On 2nd publish instance I can see the username of loggedin user in access log but the same user is not present in useradmin and request shows 404.

How can I ensure that users are synchronized between the 2 publish instances automatically so that we dont get 404 errors ?

Users on publish instances will be separate from author instance, those will be website visitors authenticated via SSO. Author instance does not have SSO.

Thanks!

dispatcher stickyness can solve this till synchronization take place.

@ankitg2807 You need to configure user synchronization between publishers.
