[SAC] LDAP maintenance

We have some LDAP maintenance that we need to do, and I would like to try and pin down a time that we can do it. No LDAP means no authentication, and it pretty much stops all Trac/SVN/Website work while it is down. We currently have two items we need to immediately tackle:
- #54 (LDAP security settings - self update, hide password) – OSGeo Fix up our permissions
- Allow SSL binding to the LDAP (so the TelaScience machines can authenticate)

Please propose a two hour block, preferably during North American waking hours, in the next two weeks that would be a good time to do this work.
