SYMPTOMS

loadTOCNode(1, ‘symptoms’); If you log on to an MIT realm, press CTRL+ALT+DELETE, click Change Password, type your existing MIT password, and then type a new, simple password that does not pass the dictionary check in Kadmind, you may receive the following error message:

Your password must be at least 18770 characters and cannot repeat any of your previous 30689 passwords. Please type a different password. Type a password that meets these requirements in both text boxes.

Note that the number of required characters changes from 17,145 to 18,770 with the installation of SP1.NOTE: This is not a common case; it occurs only when you configure Windows 2000 to authenticate against an MIT Kerberos domain.”

Favorite part of the error message, “The number of required characters changes from 17,145 to 18,770 with the installation of SP1”
