I am unable to register a database in the ArcGIS Server Manager (ArcGIS Server Manager >Site>Data Stores>Register>Database). When I try to import the .sde file a portal login prompt appears and when I enter my credentials the 'Unable to access the authentication service' error below appears. Note: We use IWA to authenticate so I pretty sure this login prompt shouldn't appear if configured correctly.
Researching the error I found that installing an intermediate certificate to link an intermediate certificate to link the SSL certificate to the trusted root CA may solve the issue. Unfortunately after doing this on the server and portal, the error is still present.
It's weird, but I am able to register a database in ArcMap with no problem. Just in ArcGIS Server Manager does this error exist.
Environment: ArcGIS Enterprise 10.6.1, federated portal using IWA. Error is present in both IE and Chrome
Any help would be appreciated.
Sorry to here about your troubles. I also entered an Esri case with this issue and it resulted in declaring it a 10.6.1 bug. As of today the bug's status is "In Product Plan." BUG-000116672.
As a work around I am still registering the databases in ArcMap like I mentioned above.
I tried this work around as well because I have the same issue (on 10.7.1) but it does not change anything.
We also added the patch security 2, in case it would help but we don't see any changes so far.
I opened a case with esri to see how we can fix this.
If someone has another work around I am interested.
It has been very difficult to me. For my case, the portal crashed.
However, I managed to extract all data, and now I am rebuilding all of the workflow, automation, webmaps and dashboards.
It's taking some time because of the volume of data.
Maybe tell us if you would need much support this way.
