If we did a database, it would be Oracle. MySQL is nice for many things, but the absolute reliability and stability we require will push us into our existing Oracle infrastructure. Yup. I know that LDAP writes are expensive, but according to our LDAP administrators we have such a robust and fault-tolerant system that the writes shouldn't be a problem, even at the loads our system experiences (About 200-300 simultaneous users at peak time). Take that for what you will. :) Seriously though, I don't expect it to be that big of a problem. Most of our users are checking mail between classes or en route to another location. I expect a BIG surge when we go live with it, then for it to slack down to relative noise (Compared to the hammering our IMAP servers take on a daily basis). > Another issue is the design of the tree and the ACLs put in there.

The design phase is going to take a lot of time not only because I don't know enough about LDAP at the moment (My focus is WebMail; we have an entire team devoted to just LDAP), but it is uncharted territory for everyone here. > I believe IMP has implemented the functionality you look for.

I've also looked at Rolodap as well. I wouldn't expect much out of me for a while. Design & requirements for this will require a lot of work and a lot of meetings. Maybe I'll let everyone look at our plan once we're close to beginning implementation. Show you all how an academic institution works. :-D or :-( depending on your point of view. :) Lee -- "If she were white and male, she would be David Duke,� Professor Emeritus Peter Swartz, commenting on Cynthia McKinney (http://www.cornellreview.org/viewart.cgi?num=304) See Cynthia McKinney ask for money Rudy Guiliani returned to the donor: http://www.savannahnow.com/stories/103101/OPEDbarton.shtml ------------------------------------------------------- This SF.net email is sponsored by: SF.net Giveback Program.
