The firewall provides a local database for storing user and group information. You can configure the firewall to use this local database to authenticate users and control their access to the network. The local database is a good choice over LDAP or RADIUS when the number of users accessing the network is relatively small. Creating entries for dozens of users and groups takes time, although when the entries are in place they are not difficult to maintain.
The number of users supported by the local database on the firewall varies by platform is shown in Maximum Number of Supported Users by Platform. The maximum overall user limit is equal to the maximum number of SSO users and the maximum number of native users is equal to the maximum number of SSO users. The maximum web users is the maximum combined user logins from the web and the GVC, SSL-VP, and L2TP clients.
