Rights required for polling / ldap auth. + more!

First off, what a great piece of software. I never thought I'd see such a product that works as good as this does right out of the box.

And now some questions..

What specific permissions does the polling user require on the monitored host in order to gather the event logs? I want to avoid adding a service account to the local Administrators group.

Why can't I set anything less than a 10 minute polling interval?

Are there any plans to add the ability to login to Eventlog Analyzer using LDAP authentication? I'm not too fond of the 10 character limit on the password.

I'm also wondering about the search function. Is there any way to globally search for a certain string that would appear in a log file? I find this very useful, but I don't see any other way of doing it other than within the "Complete View" window.

Thanks!
