I found the issue. I changed the sasl.mechs system property from GSSAPI,PLAIN to PLAIN and then everyone was able to login. Could it be a system bug? As far as I remember, I’ve set GSSAPI trying to make SSO works and it was not an issue in Openfire 4.0.3.
I’m not very familiar with this part, but i think there was a change related to GSSAPI in the latest version. @speedy can provide more information on that.
yep…thats likely the issue. spark 2.7.4 would fall back to IQ:auth, with OF 4.0.3, but IQ:Auth was removed in 4.1. With spark 2.8.x smack 4 is used, which then removed iq auth from spark.
Updating spark should fix your issue. If you can’t deploy an updated version of spark, another alternative might be to install the non-sasl auth plugin. Since iq auth is depreciated and not considered secure; Id suggest updating spark.
