LDAP

Could someone give me the readers digest version of what
LDAP is all about. I'm running qmail at work and we
really need to figure out how to get some type of
distributed addressbook for my Outlok users.
Will LDAP rescue me? If not, does anyone have anything
they have used to resolve such a problem.
