Hi All,

I am trying to upgrade jboss from existing 3.2.1 to 4.0.3SP1 in my application.
I am using win-XP-SP2, openLDAP 1.8.8.7, jdk 1.4.1_02, junit-3.8.1
openLDAP is used to authenticate users.
After moving to new jboss the following exception is generated on first ejb call.
Also the users are not getting authenticated. The following exception is generated.

The login-conf.xml entry for ldap looks like

<application-policy name="LDAPModule">

<login-module flag="required" code="org.jboss.security.auth.spi.LdapLoginModule">
<module-option name="java.naming.factory.initial">com.sun.jndi.ldap.LdapCtxFactory</module-option>
<module-option name="java.naming.provider.url">ldap://localhost:389</module-option>
<module-option name="java.naming.security.authentication">simple</module-option>
.
.
.
.
.
</login-module>

</application-policy>

Is someone having any idea as to what is happening here ?

Thanks,
Amar
