Active Directory and LDAP Books
I've been thinking about getting a solid book on Active Directory and LDAP. The two books I have been thinking of getting are both by O'Reilly ("Active Directory Second Edition" ISBN: 0596004664 and "LDAP System Administration" ISBN: 1565924916). I'm getting sick of only buying these Exam Cram type books and I want to start getting books that will give me lots of information on one specific area. If anyone knows about the quality of these books, then please let me know.
