Test case: On Ubuntu 14.04 on amd64, install krb5-admin-server and krb5-kdc.
kdb5_util -W -r T create -s awk 'BEGIN{ for (i = 0; i < 1024; i++) { printf("ank -randkey a%06d\n", i) } }' /dev/null | kadmin.local -r T For me, kadmin.local begins consuming nearly 100% CPU starting at "a000762". This implies that sites with more than a few hundred principals are likely to find running a KDC using the 14.04 krb5 packages impossible. ** Changed in: krb5 (Ubuntu) Status: New => Confirmed -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1347147 Title: krb5 database propagation enters infinite loop To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/krb5/+bug/1347147/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
