Hello, I have a problem with SSO since Spark 2.7.x prerelease (build 66x). Openfire server 3.9.1 3.9.2 works fine with Spark 2.6.3 and worked with 2.6.2 and 2.6.1.
But when I change client to Spark 2.7.0 or 2.7.1 on the same machine - couldn’t connect to Openfire server via SSO. Plain password login has no issues, only SSO. Account (kerberos realm) detection seems correct. I’ve tried cleaning settings (removing %APPDATA%\Spark), various SSO modes - krb5.ini, DNS and Manual specification, but no luck.
Because of that I’m delaying upgrade from Spark 2.6.x and Openfire 3.9.x to 2.7.x and 3.10.x respectively. Any suggestions?
Maybe it is some Java mismatch. I think 2.6.3 used 1.7.0_5x also.
Btw, Spark login with SSL was fixed in Openfire 3.10.2. So 2.6.3 should be able to login. Not sure about the SSO though. Also, there is an issue if you are using LDAPS. 3.10.2 with LDAPS (LDAP over SSL)
