Enabling Individual CM Node Login in a Load Balanced CM Sitecore v9.3 Environment
Recently we upgraded a client from Sitecore v8.2 to v9.3. They required 3 load balanced Content Management (CM) servers in the upgraded environment. We stood up the new environment that included the following servers: CM-TEST-1 (CM Node 1) CM-TEST-2 (CM Node 2) CM-TEST-3 (CM Node 3) IDENTITY-TEST (Identity Server) Login worked fine using the LB URL: https://cm-test.client.com/sitecore . Sitecore redirects you to the Identity Server as it should and we can sign in there using a local Sitecore account or the user's Active Directory account. (We had also integrated AD using ADFS) Then they told us that they needed to be able to sign in to an individual CM node sometimes when they are troubleshooting issues and are trying to figure out if it is a problem with an individual server. So I tried signing in to a single CM node using this URL https://cm-test-1.client.com/sitecore . What I noticed was that after authenticating I was redirected back to the LB URL - https://cm-test.client
