i've posted it to google code issues page but given a number of open issues i decided to link it here to (hopefully) get your attention. issue details are here:
http://code.google.com/p/yubikey-val-se ... etail?id=7basically i've made 1.2 ykval to work with RHEL in late decembler, but now no success with running 2.1. and we potentially would use sync features with multiple internal validation servers.
it would be really great if ykval would be more portable or at least clearly defined a list of dependencies (php, mysql, libcurl versions which works with it) or consist of self-containing package without external dependencies (as i think that many people would run it not on dedicated machines but in existing infrastructure). given the recent outages on hosted validation platform i think that mature ykval source is becoming more and more critical.
EDIT: i've posted patches
here and
here.
