I am trying to setup pam (with su for starters) on a solaris 9 system.
Its up to date with all the recommended patches.

I have a valid krb5.conf file in /etc/ and sym-linked to
/etc/krb5/krb5.conf. It has the following in libdefaults:
default_tkt_enctypes = des-cbc-crc
default_tgs_enctypes = des-cbc-crc

I created a keytab and symlinked it to /etc/krb5/krb5.keytab.

# klist -e -k /etc/krb5/krb5.keytab
Keytab name: FILE:/etc/krb5/krb5.keytab
KVNO Principal
2 host/vmtest2c.sandia.gov@dce.sandia.gov (DES-CBC-CRC)
2 host/vmtest2c.sandia.gov@dce.sandia.gov (DES-CBC-MD5)

I have my /etc/hosts file with (IP address X to protect the innocent):

# cat /etc/hosts
# Internet host table
# localhost
134.253.X.X vmtest2c.sandia.gov vmtest2c loghost

I added the following to my pam.conf:

su auth sufficient pam_krb5.so.1
su account sufficient pam_krb5.so.1

When I go to su as a Kerberos account I get:

bash-2.05$ su drwachdz
Enter Kerberos password for drwachdz:
authentication failed: Bad encryption type

The log files show:
Jun 29 16:35:06 vmtest2c su: [ID 537602 auth.error] PAM-KRB5 (auth):
krb5_verify_init_creds failed: Bad encryption type

Any ideas?
