Hi there, I'm currently trying to use the 'AD Trust for Legacy Clients' freeIPA setup (described here: http://www.freeipa.org/images/0/0d/FreeIPA33-legacy-clients.pdf) to be able to autenticate AIX 7.1 clients against an AD domain using LDAP. After the trust was created all seems to work well on the freeIPA server. I can also do a lookup of AD users and groups on an AIX test server.
But as soon as I want to log in on the AIX system I get an SSSD error on the freeIPA server in krb5_child.log (debug_level = 10): (Thu Mar 19 16:20:42 2015) [[sssd[krb5_child[12775]]]] [sss_child_krb5_trace_cb] (0x4000): [12775] 1426778442.590260: AS key obtained for encrypted timestamp: aes256-cts/2F5D (Thu Mar 19 16:20:42 2015) [[sssd[krb5_child[12775]]]] [sss_child_krb5_trace_cb] (0x4000): [12775] 1426778442.590326: Encrypted timestamp (for 1426778442.525165): plain 301AA011180F32303135303331393135323034325AA105020308036D, encrypted 9B3299264F09E50D63D84B385A09A4C64D44116A02B58FFF12830B39F88722CD9B792F5ABA0653578DE9138B91D29C17C197453D8B8A5E7A (Thu Mar 19 16:20:42 2015) [[sssd[krb5_child[12775]]]] [sss_child_krb5_trace_cb] (0x4000): [12775] 1426778442.590349: Preauth module encrypted_timestamp (2) (flags=1) returned: 0/Success (Thu Mar 19 16:20:42 2015) [[sssd[krb5_child[12775]]]] [sss_child_krb5_trace_cb] (0x4000): [12775] 1426778442.590360: Produced preauth for next request: 2 (Thu Mar 19 16:20:42 2015) [[sssd[krb5_child[12775]]]] [sss_child_krb5_trace_cb] (0x4000): [12775] 1426778442.590384: Sending request (238 bytes) to EXAMPLE.CORP (Thu Mar 19 16:20:42 2015) [[sssd[krb5_child[12775]]]] [sss_child_krb5_trace_cb] (0x4000): [12775] 1426778442.591325: Resolving hostname dct020.example.corp.
