Changing encryption values on Kerberos server

To operate with Windows^® workstations, the Kerberos server default encryption settings need to be changed so that clients can be authenticated to the i5/OS^® PASE Kerberos server. To change the default encryption settings, you need to edit the kdc.conf file located in the/etc/krb5 directory by following these steps:

1. In a character-based interface, enter edtf '/var/krb5/krb5kdc/kdc.conf' to access the kdc.conf file.

2. Change the following lines in the kdc.conf file:

   supported_enctypes = des3-cbc-sha1:normal 
   arcfour-hmac:normal aes256-cts:normal 
   des-cbc-md5:normal des-cbc-crc:normal

   to

   supported_enctypes = des-cbc-crc:normal des-cbc-md5:normal
