> Key: HTTPCLIENT-1736
> URL: https://issues.apache.org/jira/browse/HTTPCLIENT-1736
> Project: HttpComponents HttpClient
> Issue Type: Improvement
> Components: HttpClient
> Affects Versions: 4.5.2
> Reporter: Karsten Spang
> Assignee: Oleg Kalnichevski
> Fix For: 4.5.3
>
>
> In {{GGSSchemeBase.generateGSSToken}}, line 133 in version 4.5.2:
> {code:java}
> gssContext.requestCredDeleg(true);
> {code}
> For Kerberos, this means that the client will forward the to TGT to the server. First, I don't see why you would want that, as that is an unnecessary security risk. Second, I have a problem with my {{SecurityManager}} (Oracle's in-database Aurora security manager), so I am unable to create a permission for this that works.
> I suggest to change this to
> {code:java}
> gssContext.requestCredDeleg(false);
> {code}
> There might be situations where a client application would actually want to pass the TGT, but it should be possible to control this.
