Yes, this would be a new implementation. I have not yet installed
OpenLDAP, so I am using the documentation available via the

I've been using the Administrator's Guide from the web site. I just
downloaded the 2.3.4 release and the guide in the tarball is dated 10
May 2005, just like the version on the web site. Looks like it needs
updating to synchronize with the new/removed configuration keywords.
The manpage I've been using is also the one on the web site, from
2.3-Release, which I had presumed would be updated whatever the release

Right, that's why I was wondering if there was a "require tls" or
equivalent. It seems like "security tls=128" or the like will do what

OK, then apparently the manpage _is_ canonical.

So it would seem the short answer to my question is I either choose one
of the ones listed in the manpage, or do something like add the
additional hash support to crypt() itself, which doesn't appeal to me
since I'd be changing one of the distributed-with-the-OS-core
Would it a big deal to make a feature request for something like
SHA-256, SHA-512, and/or Blowfish support?
