Tell me doing wrong. Openfire 4.1.4 Win , Spark 2.8.3 + SSO

Настраиваю как Openfire с поддержкой SSO [CorpDocs]

Spark при коннекте говорит:

Unable to connect using Single Sing-On. Please check your principal and server setings.

spark.properties :

hostAndPort=True

xmppHost=sdrk.strdp.local

xmppPort=5222

ssoMethod=dns

ssoEnabled=True

server=stroydepo.local

useHostnameAsResource=True

showEmptyGroups=True

showOfflineUsers=True

offlineGroupVisible=False

starthidden=False

loginAsInvisibleEnabled=False

debuggerEnabled=True

output.log :
