This patch works as expected, but I'm not sure that it fixes original issue, because there is still a window, although 10s shorter, where the cache is empty and a 'getent passwd' call will return immediately without any data. This window can be quite large if the LDAP server is slow or there are a lot of users and groups to enumerate. If there was a 'getent passwd' call during the initial enumeration it looks that new 'getent passwd' still return nothing until enum_cache_timeout is over. So maybe if we do not want to block the early enumeration request we should not set the timeout until the cache if filled. bye, Sumit > > Fixes https://fedorahosted.org/sssd/ticket/616 > > - -- > Stephen Gallagher > RHCE 804006346421761 > > Delivering value year after year. > Red Hat ranks #1 in value among software vendors. > http://www.redhat.com/promo/vendor/ > -----BEGIN PGP SIGNATURE----- > Version: GnuPG v1.4.11 (GNU/Linux) > Comment: Using GnuPG with Fedora - http://enigmail.mozdev.org/ > > iEYEARECAAYFAkz/+McACgkQeiVVYja6o6MjTgCdHQWbZOOKtcURTbl29PV/YR0u > j7wAoKAm7stVwQT89xdz3vZyN/w6vMZU > =xOOZ > -----END PGP SIGNATURE----- _______________________________________________ sssd-devel mailing list sssd-devel@lists.fedorahosted.org https://fedorahosted.org/mailman/listinfo/sssd-devel
