Hello. I ask to help, openfire authorization ntlm, client Spark. Can I somehow @connect from a non-domain?
In my server config - for NTLM
sasl.gssapi.config = /etc/openfire/gss.conf
sasl.gssapi.debug = false
sasl.gssapi.useSubjectCredsOnly = false
sasl.mechs = GSSAPI
sasl.realm = REALM.LOCAL
xmpp.fqdn = openfireserver.realm.local
add PLAIN to sasl.mechs
please keep in mind that there are security concerns related to using PLAIN, and they should be researched before using it to determine if the risk is acceptable to you and your organization.
