[Bug 1119465] Re: credential verification failed: KDC has no support for encryption type

[Russ Allbery]

Reassigning to krb5, as:

Feb 8 15:38:09 vpn-gw-ausfall openvpn[9031]: pam_krb5(openvpn-
krb5:auth): (user hildeb) credential verification failed: KDC has no
support for encryption type

is an error message from the underlying Kerberos library that libpam-
krb5 can't do anything about.  libpam-krb5 itself doesn't know (or care)
anything about enctypes.

** Package changed: libpam-krb5 (Ubuntu) => krb5 (Ubuntu)

  Basically this is http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=669127 but on Ubuntu.
  I'm trying to authenticate against Active Directory, and starting with version 1.10+dfsg~beta1-2ubuntu0.3 of the kerberos packages I'm getting these errors:
