Hi
1)
Can you provide client sample code using SASL Security ( for now PLAIN example would be enought ).
( or just add this example to https://docs.jboss.org/author/display/AS71/Developer+Guide#DeveloperGuide-EJBinvocationsfromaremoteclientusingJNDI https://docs.jboss.org/author/display/AS71/Developer+Guide#DeveloperGuide-EJBinvocationsfromaremoteclientusingJNDI )
2)
I looked in source code of org.jboss.sasl.JBossSaslProvider.java ( jboss-sasl-1.0.0.Beta9.jar )
Ony SASL MECH I see here are:
"ANONYMOUS"
"PLAIN",
"DIGEST-MD5",
"JBOSS-LOCAL-USER"
Could you also add "GSSAPI" ( here how to from Darran Lofthouse http://community.jboss.org/docs/DOC-17302 http://community.jboss.org/wiki/SASLAndKerberos )
Basically I would like to do this but with AS7.1:
http://community.jboss.org/docs/DOC-16137 http://community.jboss.org/wiki/EJB3AuthenticationWithSPNEGO
I tried to call remote ejb after sucessfull JAAS Login, but JAAS Login Context seams to not get propagatet to Server over Jboss Remote...
Here how I tried ( the same Code but calling Web URL Secured with SPNEGO works, so KRB5 Java Setup is ok) :
