Additional note: This problem ONLY occurs if dns_lookup_kdc = true and no KDCs are set. If one of the 2003 Servers is defined manually and dns lookup is off, ticket is retreived correctly. Sorry, I was wrong, problem even exists if KDC is specified manually. After re-verification it really turned out that it only occurs on service discovery.
default_tkt_enctypes = aes-256-cts arcfour-hmac-md5
default_tgs_enctypes = aes-256-cts arcfour-hmac-md5
works as well. So I wonder why default enctypes needs to be set if dns lookup is enabled?
This message is a reminder that Fedora 13 is nearing its end of life. Approximately 30 (thirty) days from now Fedora will stop maintaining and issuing updates for Fedora 13. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as WONTFIX if it remains open with a Fedora 'version' of '13'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version prior to Fedora 13's end of life. Bug Reporter: Thank you for reporting this issue and we are sorry that we may not be able to fix it before Fedora 13 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora please change the 'version' of this bug to the applicable version. If you are unable to change the version, please add a comment here and someone will do it for you. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete. The process we are following is described here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping Fedora 13 changed to end-of-life (EOL) status on 2011-06-25. Fedora 13 is no longer maintained, which means that it will not receive any further security or bug fix updates. As a result we are closing this bug. If you can reproduce this bug against a currently maintained version of Fedora please feel free to reopen this bug against that version. Thank you for reporting this bug and we are sorry it could not be fixed. |
Description of problem: We got a mixed network of Windows 2003 and 2008R2 KDCs. kinit successfully retreives a ticket if service discovery leads to one of the 2008R2 KDCs, if it leads to a 2003 Server, I got an error message like: KDC has no support for encryption type If session key enctypes are forced using: default_tkt_enctypes = arcfour-hmac-md5 default_tgs_enctypes = arcfour-hmac-md5 everything works fine but shouldn't auto-negotiation work as well?
