<html><body>Hello, I am starting to see some issues with a few RHEL7 boxes I have been enrolling to my RHEL 6 IPA server regarding encryption. RHEL 7 client Red Hat Enterprise Linux Server release 7.1 (Maipo) sssd-ipa-1.12.2-58.el7_1.18.x86_64 ipa-client-4.1.0-18.el7_1.4.x86_64 RHEL 6 Server Red Hat Enterprise Linux Server release 6.8 (Santiago) sssd-ipa-1.13.3-22.el6_8.4.x86_64 ipa-server-3.0.0-50.el6.1.x86_64 The RHEL 7 client shows this in messages Nov 15 21:13:02 server1 [sssd[ldap_child[26640]]]: Program lacks support for encryption type Nov 15 18:08:51 server1 [sssd[ldap_child[7774]]]: Failed to initialize credentials using keytab [MEMORY:/etc/krb5.keytab]: Decrypt integrity check failed. Unable to create GSSAPI-encrypted LDAP connection. I am also not seeing host certs for them on the ipa server but I do see them on the local box.
