how two ADFS server work in one ADFS farm RRS feed

  • Question

  •  I've setup two ADFS servers, the first one showing primary during the installation, and the one showing secondary. I want to know how this two works together. will it be one active, and the other standby? in the meantime, how its database works?  will it be keep caching the user's auth info? will it be running some clean up? if yes, how often?

  • It kind of depends if they are using WID/SQL and are loadbalanced etc.

    If you are using WID the configuration between the nodes is taking place via pull-method.
    The secondary-servers are reaching out to the primary member and retrive the latest copy of the primarys WID database/configuration. The sync between the nodes goes over port 80. 

    There is nothing "cached" on the servers during authentication (more then normal login events etc).
    So the login information/event will only show up on the server that actually handeled the login request from the user. 

    You do not need to run any clean up-stuff, all the vital information for making auth/SSO works is stored in a cookie in the users browser on the client.
