[Pki-users] Questions on customizing certificate profiles

[Kevin Unthank]

Hi Arshad,

Obviously, there are differences between RHCS8 and the latest release
of Dogtag. Generally, new feature development takes place in dogtag
and some of those features find there way back into RHCS8. Bug fixing
often occurs first in RHCS8 and those fixes are ported to dogtag.

PKI with only SHA-2 hashes is a fix that was made in the RHCS8
code tree and released in both source binary form in errata
RHBA-2009-1602. That fix will make it into dogtag builds but I can't
commit to a specific release or date when this will happen.

Until then it should be possible to work around the problem by using
pkisilent or the renewal method suggested by Andrew.

Cheers,
Kev
