2 Browse to Administration > Single Sign-On > .
3 Click the Policies tab and select Lockout Policy.
4 Click Edit.
5 Edit the parameters.
Option Description
Description
Optional description of the lockout policy.
Max number of failed login attempts
Maximum number of failed login aempts that are allowed before the
account is locked.
Time interval between failures
Time period in which failed login aempts must occur to trigger a lockout.
Unlock time
Amount of time that the account remains locked. If you enter 0, the
administrator must unlock the account explicitly.
6 Click OK.
Edit the vCenter Single Sign-On Token Policy
ThevCenter Single Sign-On token policy species the clock tolerance, renewal count, and other token
properties. You can edit the vCenter Single Sign-On token policy to ensure that the token specication
conforms to your corporation's security standards.
Procedure
1 Log in to the vSphere Web Client.
2 Select Administration > Single Sign-On, and select .
3 Click the Policies tab and select Token Policy.
The vSphere Web Client displays the current conguration seings. If you have not modied the
default seings, vCenter Single Sign-On uses them.
4 Edit the token policy conguration parameters.
Option Description
Clock tolerance
Time dierence, in milliseconds, that vCenter Single Sign-On tolerates
between a client clock and the domain controller clock. If the time
dierence is greater than the specied value, vCenter Single Sign-On
declares the token invalid.
Maximum token renewal count
Maximum number of times that a token can be renewed. After the
maximum number of renewal aempts, a new security token is required.
Maximum token delegation count
Holder-of-key tokens can be delegated to services in the vSphere
environment. A service that uses a delegated token performs the service on
behalf of the principal that provided the token. A token request species a
DelegateTo identity. The DelegateTo value can either be a solution token or
a reference to a solution token. This value species how many times a
single holder-of-key token can be delegated.
