SYMPTOMS
When a Windows 2000 account belongs to a large number (over 1,000) of groups, the Security Account Manager (SAM) requires a large amount of time to do the group evaluation during account logon. During this time, the administrator cannot recover the domain controller because the administrator will have a token that has more than 1,024 security identifiers (SIDs), and Local Security Authority (LSA) will ultimately fail the logon because of too many SIDs. Also, the failure will take a long time to appear because of the increased SAM activity.

A user that is given the privilege to add other users to groups could add a user to too many groups, in which case the user would no longer be able to logon.
