Fixing the hostname references is part of it, and if you are using certificates specific to the admin-server to authenticate then they need to be updated/replaced as well to avoid things like instance/realm or nss hostname check problems. The config files should contain lots of references to the old hostname (unless a magical script fixed them when you weren't looking), and those must be changed. Don't forget to look places like nss.conf, and weirder areas like filnames of auth keys (and make sure to check silly spots like hosts.conf to make sure NetworkManager or whatever didn't append the new hostname in there somewhere (like an unused IPv6 line), or mix and match old and new hostnames, as this can break random authentication things related to Kerberos and NSS). Some files have hostname info tagged at the end of them, and things that point to them must be lined up. I would start by walking myself back through manual setup steps as if I were setting up admin-server on a new system to make sure I didn't miss anything and then recreating my authentication keys if necessary. Fixing a partially broken authentication setup *sucks*. In situations like that if the machine isn't the sole server (a slave is out there somewhere), I'll just re-install the server packages to make sure nothing is missed and then replicate back from the slave or a backup because re-setting nitpicky manual setups without doing them 100% from the beginning can be a real pain. -Iwao -- 389 users mailing list 389-users@xxxxxxxxxxxxxxxxxxxxxxx https://admin.fedoraproject.org/mailman/listinfo/389-users
