We have two nodes in a clustered enviornment (Alfresco and tomcat) with passthru authentication along with ldap and NTLM configured. protocol order is TCPIP, NETBIOS. It works fine most of the time, but sometimes and for some users authentication screen comes again and again.
Below is stack trace. Any pointer will be helpful.
