We were unfortunate to include this setting into one of the early sssd.conf examples and people have been copying it around ever since though we strongly recommend against enabling it. <blockquote cite="mid:537E0B7D.4030006@damascusgrp.com" type="cite"> <tt> </tt><tt>[domain/foo.net]</tt><tt> </tt><tt> </tt><tt>cache_credentials = True</tt><tt> </tt><tt>krb5_store_password_if_offline = True</tt><tt> </tt><tt>ipa_domain = foo.net</tt><tt> </tt><tt>id_provider = ipa</tt><tt> </tt><tt>auth_provider = ipa</tt><tt> </tt><tt>access_provider = ipa</tt><tt> </tt><tt>ipa_hostname = rm266ws-a.foo.net</tt><tt> </tt><tt>chpass_provider = ipa</tt><tt> </tt><tt>ipa_dyndns_update = True</tt><tt> </tt><tt>ipa_server = _srv_, 192.168.2.61, 192.168.2.62, 192.168.2.63</tt><tt> </tt><tt>ldap_netgroup_search_base = cn=ng,cn=compat,dc=foo,dc=net</tt><tt> </tt><tt>ldap_tls_cacert = /etc/ipa/ca.crt</tt><tt> </tt><tt>[sssd]</tt><tt> </tt><tt>services = nss, pam, ssh</tt><tt> </tt><tt>config_file_version = 2</tt><tt> </tt><tt> </tt><tt>domains = foo.net</tt><tt> </tt><tt>[nss]</tt><tt> </tt><tt> </tt><tt>[pam]</tt><tt> </tt><tt> </tt><tt>[sudo]</tt><tt> </tt><tt> </tt><tt>[autofs]</tt><tt> </tt><tt> </tt><tt>[ssh]</tt><tt> </tt><tt> </tt><tt>[pac]</tt><tt> </tt> On the other hand, if you meant something else, then I hope the answer's in the file. ;-) <div class="moz-cite-prefix">On 05/22/2014 10:15 AM, Dmitri Pal wrote: </div> <blockquote cite="mid:537E066E.3010301@redhat.com" type="cite"> <meta content="text/html; charset=ISO-8859-1" http-equiv="Content-Type"> <div class="moz-cite-prefix">On 05/22/2014 09:43 AM, Bret Wortman wrote: </div> <blockquote cite="mid:537DFEF2.5020602@damascusgrp.com" type="cite">What we're seeing is slow GDM logins, ssh authentications, and "sudo -i" responses on this network.

At best, a second connection might be a second faster, but will revert within an hour or so. </blockquote> Have you compared sssd.conf from clients in these two networks? Do you use enumeration? Increasing debug level and looking at the logs will help you to understand what part takes most time. These logs will be helpful for you/us to see if/what the problem is/are. <blockquote cite="mid:537DFEF2.5020602@damascusgrp.com" type="cite"> On 05/22/2014 09:36 AM, Rob Crittenden wrote: <blockquote type="cite">Bret Wortman wrote: <blockquote type="cite">Where should my clients be getting the contents of /etc/openldap/certs from?

On the slower one, clients' /etc/openldap/certs directories are either missing or empty; on the faster network, clients have certs in these directories. Is this important, and if so what could be going wrong on my slower network that might cause the certs to not get distributed or created properly? </blockquote> These are not the droids you are looking for... Can you clarify what you mean by IPA authentications? sssd should be handling that, and while a first auth over a slow link might be slow subsequent usage should be quite fast. rob </blockquote> <fieldset class="mimeAttachmentHeader"></fieldset> <pre wrap="">_______________________________________________ Freeipa-users mailing list <a moz-do-not-send="true" class="moz-txt-link-abbreviated" href="mailto:Freeipa-users@redhat.com">Freeipa-users@redhat.com</a> <a moz-do-not-send="true" class="moz-txt-link-freetext" href="https://www.redhat.com/mailman/listinfo/freeipa-users">https://www.redhat.com/mailman/listinfo/freeipa-users</a></pre> </blockquote> <pre class="moz-signature" cols="72">-- Thank you, Dmitri Pal Sr. Engineering Manager IdM portfolio Red Hat, Inc.</pre> <fieldset class="mimeAttachmentHeader"></fieldset> <pre wrap="">_______________________________________________ Freeipa-users mailing list <a moz-do-not-send="true" class="moz-txt-link-abbreviated" href="mailto:Freeipa-users@redhat.com">Freeipa-users@redhat.com</a> <a moz-do-not-send="true" class="moz-txt-link-freetext" href="https://www.redhat.com/mailman/listinfo/freeipa-users">https://www.redhat.com/mailman/listinfo/freeipa-users</a></pre> </blockquote> <fieldset class="mimeAttachmentHeader"></fieldset> <pre wrap="">_______________________________________________ Freeipa-users mailing list <a moz-do-not-send="true" class="moz-txt-link-abbreviated" href="mailto:Freeipa-users@redhat.com">Freeipa-users@redhat.com</a> <a moz-do-not-send="true" class="moz-txt-link-freetext" href="https://www.redhat.com/mailman/listinfo/freeipa-users">https://www.redhat.com/mailman/listinfo/freeipa-users</a></pre> </blockquote> <pre class="moz-signature" cols="72">-- Thank you, Dmitri Pal Sr. Engineering Manager IdM portfolio Red Hat, Inc.</pre> <fieldset class="mimeAttachmentHeader"></fieldset> <pre wrap="">_______________________________________________ Freeipa-users mailing list <a class="moz-txt-link-abbreviated" href="mailto:Freeipa-users@redhat.com">Freeipa-users@redhat.com</a> <a class="moz-txt-link-freetext" href="https://www.redhat.com/mailman/listinfo/freeipa-users">https://www.redhat.com/mailman/listinfo/freeipa-users</a></pre> </blockquote> </body> </html>
