Description Dmitri Pal 2012-03-06 12:02:18 EST
This bug is created as a clone of upstream ticket:

DES is completely disabled in 2.2 servers. We need a way to be able to generate DES keys at least for older NFS clients and servers.

I tried adding allow_weak_crypto = yes to libdefaults of the IPA server krb5.conf and adding support for the enc type but was still unable to use ipa-getkeytab from a RHEL-5 client.

I added this to LDAP:
dn: cn=$REALM,cn=kerberos,dc=greyoak,dc=com
krbSupportedEncSaltTypes: des-cbc-crc:normal
krbSupportedEncSaltTypes: des-cbc-crc:special
krbDefaultEncSaltTypes: des-cbc-crc:special
