Linux: Mount a Windows share with kerberos authentication

Hi,

First of all install the necessary pakets.

Linux: Kerberos authentification against Windows Active Directory

Hi,

here are some steps to use kerberos authentification against a active directory with OS Version Windows Server 2008 R2 or later on your linux machine.

The default krb5 configuration implementation of the most linux distributions did not work out of the box. I assume that the REALM in /etc/krb5.conf is already configured.

Typical error messages are:

kinit: KDC has no support for encryption type while getting initial credentials
kinit: KDC reply did not match expectations while getting initial credentials

michael@debdev:~# kinit  michael@subdomain.domain.local
Password for michael@subdomain.domain.local:
kinit: KDC has no support for encryption type while getting initial credentials

To eliminate the “KDC has no support for encryption type while getting initial credentials” issue change the default encryption type in the libdefaults section of the /etc/krb5.conf file.
