I work at a library and just installed a jabber server to test in-house chatting…looking around for a jabber client and came across Spark which looked the cleanest and easiest to use, especially with SSO…I am not running OpenFire but will be look at that next…
My question is that the first time I tried SSO, it appeared to work fine…but while playing around, I can no longer get SSO to work…meaning that I get the “Unabled to connect using Single Sign-On. Please check your principal and server settings.” Any idea on why this is?
Also, as part of the troubleshooting, be interested on what exactly the SSO part does? Meaning, how is does it work to create a user SSO?
