Emmanuel Lecharny updated DIRSERVER-2059:
-----------------------------------------
    Component/s: kerberos

> Kerberos Password Change Server Failure
> ---------------------------------------
>
>                 Key: DIRSERVER-2059
>                 URL: https://issues.apache.org/jira/browse/DIRSERVER-2059
>             Project: Directory ApacheDS
>          Issue Type: Bug
>          Components: kerberos
>    Affects Versions: 2.0.0-M19
>         Environment: Linux
>            Reporter: Craig McLure
>            Priority: Major

> I've been trying to get kpasswd to correctly change a users password, but it always failed,
after doing some digging and debugging, I discovered the following:
> *org.apache.directory.server.kerberos.ChangePasswordConfig*
> Primary realm is never set, resulting in inheritance of default EXAMPLE.COM realm regardless
of the realm configured. Adding:
> {{this.setPrimaryRealm( kdcConfig.getPrimaryRealm() );}}
> into the constructor resolved this.
> *org.apache.directory.server.kerberos.changepwd.service.ChangePasswordService*
> in {{extractPassword}} there's the following check:
> {{if( authenticator.getSeqNumber() != privatePart.getSeqNumber() )}}
> However, the Authenticator's Sequence Number is never set, resulting in this throwing
a NullPointerException. Commenting out the check, admittedly unwise, allows the code to proceed
normally.
> With both these changes, password changing via kpasswd is possible again.
