Currently ipa-client depends on python-krbv. It is believed to be needed only for uninstalling to get the default kerberos realm so /etc/krb5.keytab can be cleaned up. However, python-krbv is not packaged for RHEL6 and this is causing a dependency problem for the RHEL6 tech preview of ipa-client. Lets investigate if there are alternative mechanisms to get the default krb realm so we can remove the dependency on python-krb5.
