Federated identity management using Active Directory Federation Services
now to add second server build server 2012r2 name adfs2
export communications SSL from adfs1 and import in adfs2
run wizard for new install and add to farm ?
Basically your describe steps are right.
Did you create a FARM when you set up the first AD FS server?
we have WID no SQL db
That is no problem. WID supports up to +- 20 AD FS instances.
What about Token - encrypting / signing situation ?
Export and import the required ssl certificate(s) from the first AD FS serverbefore you start the configuration wizard on the second AD FS server.
Note: It is recommended to use a hardware or vitual load balancers for your szenario. The Windows LNB ist not right product for it.
