Thanks Huib, Ryan, Courtney (sorry I called you Catherine before!), and Platonides for your suggestions for getting the admin password sorted out! In the end, I disabled the LDAP, and had to associate my email with the Wikiadmin account (another dumb mistake, not setting up the email) in MySQL, and then was able to use the password reset function on the wiki login screen with the LDAP disabled. Have since made myself and two other LDAP accounts Bureaucrats and Sysops to prevent further foolishness. :)
Thanks again!
Nina
