I have installed ArcGIS Enterprise Builder 10.5.1 which is configured to authenticate with SAML/Shib. and both portal and server are federated to use single sign-on. When I tried to publish a service from ArcMap, is there a special option to login if the server is configured to use SAML? I am getting error message as in attached image.
Before you go down another route, I'd delete and recreate the connection to the GIS Server in Catalog. That sometimes helps to fix issues like this. There isn't another dialog to connect directly to the GIS Server that I'm aware of. There's the PORTAL login when publishing hosted feature services, but not for publishing 'classic' services.
OK, that makes sense.
Does this ring true:
When making the publisher or administrator connection within ArcCatalog or ArcMap, supply the ArcGIS for Server URL, but leave the username and password field blank, select Finish and a Window pop-up with the option to sign in using the (Security Assertation Markup Language) SAML account.
Did you find a resolution to this issue? I have come across the same issue with v10.6...
Note: I have not used Enterprise Builder but have SAML setup for a Federated Portal and I receive the same error when connecting to ArcGIS server via the 6080 and 6443 URLs. I have also tried via the Web Adaptor URL and get similar errors if I capture the traffic.
I am still not able to login from 'Publish' menu in ArcMap but there is
a work around using ArcGIS Administrator and configure the Portal
connection there.. when I use this option, it prompt me to login via
SAML, looks like that keep the session alive and I can use this
connection in ArcMap to publish. Here is more info. about this
Connected to portal as given in the
Signed into Portal for ArcGIS from ArcMap by navigating to File > sign
This resolved the issue for me. In v10.6, once I connected to the federated portal via ArcGIS Administrator I could publish to ArcGIS Server and also make administrative & publisher connections to the server.
Esri just need to update this documentation http://enterprise.arcgis.com/en/server/latest/administer/windows/about-connecting-to-arcgis-server-i... to include this information...
If the ArcGIS Server site you're connecting to is federated with a portal, provide portal credentials. If your portal uses SAML authentication, you cannot connect directly to the federated server from ArcMap.
