3.4 new kerberos Share SSO feature does not work when using IBM java

Note we are only interested in behaviour on Websphere, since that is the only stack we certify with IBM Java so please modify the steps below as appropriate.

How to reproduce?
1) build a linux+tomcat+mysql 3.4b2 alfresco with kerberos auth
2) set your env to use IBM java:

export JAVA_HOME=/usr/local/ibm-java-i386-60
export JAVA="/usr/local/ibm-java-i386-60/jre/bin/java"
export JDK_HOME="/usr/local/ibm-java-i386-60"

3) set the java security:

In JRE\lib\security\java.security. In file:

Add the following line


In jre/lib/security

create a file:

{ com.ibm.security.auth.module.Krb5LoginModule sufficient; };

AlfrescoCIFS { com.ibm.security.auth.module.Krb5LoginModule required debug=true credsType=acceptor useKeyTab="file:///etc/keys/alfrescocifs.keytab" principal="cifs/madona.example.foo"; };

AlfrescoHTTP { com.ibm.security.auth.module.Krb5LoginModule required debug=true credsType=acceptor useKeytab="file:///etc/keys/alfrescohttp.keytab" principal="HTTP/madona.example.foo"; };

com.sun.net.ssl.client { com.ibm.security.auth.module.Krb5LoginModule sufficient; }



{ com.ibm.security.auth.module.Krb5LoginModule sufficient; }


4) activate kerberos in share-config-custom.xml

cp ./shared/classes/alfresco/web-extension/share-config-custom.xml.sample ./shared/classes/alfresco/web-extension/share-config-custom.xml

(following the comments)

5) boot alfresco

From a XP client HTTP explorer (jsp client) works with SSO kerberos.

From a XP client HTTP Share fails, with error in the logs:

Expected results:
It works

a) it fails also from a Linux (firefox) client
b) On XP it fails on both IE6 and Firefox
c) when using Oracle (Sin) Java it works from a XP client (IE6 and Firefox) but still fails from Linux + firefox (see liked bug)
d) due to ALF-5205 the XP client cannot find the name of the alf seerver so you need to tell the client (for instance using the hosts file) the IP of the alf server

Yes I can too make Explorer work with Kerberos SSO on a IBM JVM.

But the issue here is not about
Explorer Kerberos SSO
but about
Share Kerberos SSO

To me only Explorer Kerberos SSO works on a IBM JVM.
Both CIFS (jira ALF-5205) and Share (this Jira) have problems.
