Locking User Accounts
As a security precaution, user accounts are disabled after five unsuccessful authentication attempts in row. This includes unsuccessful authentication attempts to Enterprise Designer, Management Console, web services, and the Client API.
As an administrator, you can re-enable a user account by logging into Management Console, editing the user, and switching the Enabled switch to On. User accounts can also be re-enabled using the Administration Utility. Users do not have the ability to unlock their own accounts.
Note: If you are using LDAP or Active Directory for authentication, the account locking
rules of these services will apply. Your LDAP or Active Directory rules may allow more
or fewer unsuccessful login attempts than Spectrum™ Technology Platform.
