A single device certificate or a chain of device certificates with issuer certificates can be installed.
The device certificate must meet the following requirements:
• The public key must be of the type "RSA" and the key length must be 2048 or 4096 bits.
• The secure hash algorithm must be of the type "SHA1", "SHA224", "SHA256", "SHA384" or
"SHA512".
Note that the secure hash algorithms "SHA1" and "SHA224" may cause compatibility
problems with your web browser.
The following applies to the "Subject" and "Issuer" fields of the device certificate and to any issuer
certificates that are installed with them: The "Distinguished Name" (DN) must contain a "CN"
(Common Name) component.
The following X509v3 extensions are tested:
• Basic constraints ("X509v3 Basic Constraints")
For the device certificate, "CA: False" must be set, for the issuer certificates "CA: True"
• Key Usage ("X509v3 Key Usage")
The field must not be empty.
• Recommendation:
The fields "Subject Alternative Name" (DNS in "X509v3 Subject Alternative Name"),
"Authority Key Identifier" (keyid in "X509v3 Authority Key Identifier") and "Subject Key
Identifier" ("X509v3 Subject Key Identifier") should also be filled in. This facilitates the
verification of trustworthiness by the web browser.

User management
In the "User management" menu, you can activate or deactivate user management. If user
management is activated, all users must log on in the login area of the WBM to be able to make
changes in the WBM. If user management is deactivated, the settings of the "WEB" user profile
are automatically applied.
Depending on your own user role and whether your user profile has been granted administrator
rights, you can manage "User profiles" in this menu.
User management
NOTICE
Save the device configuration before activating user management
Export your device configuration before you activate user management. If you experience
compatibility problems with your web browser and https encryption which require that you
restore the factory settings of the camera, this gives you the option of reverting to the previous
state.
Click the "Activate user management" button to activate user management. After user
management has been activated, each user must log on to the WBM in the login area.
