Figure 70 User Time Restrictions
User Address Restrictions
You can place network address restrictions on a directory user account, and the directory server
enforces these restrictions. See the directory service documentation for information about the
enforcement of address restrictions on LDAP clients, such as a user logging in to an iLO 2 device.
Network address restrictions placed on the user in the directory may not be enforced in the expected
manner if the directory user logs in through a proxy server. When a user logs in to an iLO 2 device
as a directory user, the iLO 2 device attempts authentication to the directory as that user, which
means that address restrictions placed on the user account apply when accessing the iLO 2 device.
However, because the user is proxied at the iLO 2 device, the network address of the authentication
attempt is that of the iLO 2 device, not that of the client workstation.
Creating Multiple Restrictions and Roles
The most useful application of multiple roles includes restricting one or more roles so that rights do
not apply in all situations. Other roles provide different rights under different constraints. Using
multiple restrictions and roles enables you to create arbitrary, complex rights relationships with a
minimum number of roles.
For example, an organization might have a security policy in which iLO 2 administrators are
allowed to use the iLO 2 device from within the corporate network but are only able to reset the
server outside of regular business hours.
Directory administrators may be tempted to create two roles to address this situation, but extra
caution is required. Creating a role that provides the required server reset rights and restricting it
to an after-hours application might allow administrators outside the corporate network, to reset the
server, which is contrary to most security policies.
Figure 71 shows how security policy dictates that general use is restricted to clients within the
corporate subnet, and server reset capability is additionally restricted to after hours.
