Exchange 2013 DAG / 2 CAS Server Multiple Logins



we are using a 2-Node Exchange 2013 DAG in a seperate Network (2-arm configuration with LOADMASTER as gateway). Everytime we´re trying to login via OWA / ECP we are getting multiple loginprompts. The only workaround to get rid of this is to use the persistence option, which is not supported / required on Exchange 2013.

While Microsoft recommends you simplify configuration and persistence is not required, the statement that persistence is not supported is incorrect. None of Microsoft guidance includes the language that it is unsupported. Persistence is a workaround for your issue, I would start by looking at your certificate configuration, here is an excellent article for your reference.
