红帽全球峰会第 7 章 Logging in to the Identity Management Web UI using one time passwords
Access to IdM Web UI can be secured using several methods. The basic one is password authentication.
To increase the security of password authentication, you can add a second step and require automatically generated one-time passwords (OTPs). The most common usage is to combine password connected with the user account and a time limited one time password generated by a hardware or software token.
The following sections help you to:
- Understand how the OTP authentication works in IdM.
- Configure OTP authentication on the IdM server.
- Configure a RADIUS server for OTP validation in IdM.
- Create OTP tokens and synchronize them with the FreeOTP app in your phone.
- Authenticate to the IdM Web UI with the combination of user password and one time password.
- Re-synchronize tokens in the Web UI.
- Retrieve an IdM ticket-granting ticket as an OTP or RADIUS user
- Enforce OTP usage for all LDAP clients
