Openfire Meetings - focus user and ofmeet-focus host?

Openfire 4.2.3. I use SSO. focus user don’t connect and focus JID don’t change.
If I delete settings:
sasl.gssapi.config C:\Program Files (x86)\Openfire\conf\gss.conf
sasl.gssapi.debug false
sasl.gssapi.useSubjectCredsOnly false
sasl.mechs GSSAPI
sasl.realm LAB.LOCAL then focus login successfully
