RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Description Dmitri Pal 2012-03-06 17:02:18 UTC

This bug is created as a clone of upstream ticket:
https://fedorahosted.org/freeipa/ticket/2471

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
