Platform Access

To use the Crater platform, you need to have a valid platform account. Depending on the platform configuration, you can choose to log in using the laboratory's LDAP account or through a Crater platform account.

If you don't see some login method entries mentioned in this document, it's normal. The available login methods depend on your platform administrator's configuration.

LDAP Login & Registration

Overview

Crater supports automatic registration and information synchronization of LDAP accounts. You don't need to manually create an account; just enter your LDAP username and password to log in.

If you are a member of the ACT Lab and have a unified authentication account, you should use this method.

Note that normally you cannot use this login method to directly log in to your LDAP or other accounts.
