joining win2003domain - old krb5 and glibc version

[jan peuker lst-deutschland de]

Hi everybody,

  I am facing a problem with my 14days old Dell Server running RHEL3(Kernel 2.4.21). I can not join a Win2003 domain with Samba3.0.9 because of "KDC reply did not match expectiations". This is afaik due to new encryption methods which are available in krb5-1.3.4 - but the system has 1.2.7. When I tried to update (using Fedora RPM's) to the more recent version it failed - because the glibc version is too old as well. I don't want to replace EL system libraries with Fedora ones so - do you know any solution?
Any help is very appreciated, thanks a lot

PS: Does anybody of you know where to get "official" support by redhat? In die RHN it only offers me the Knowledgebase...
