SSO Predefined Group: Users
Contains all users in the SSO domain
SSO Predefined Group: DCAdmins
Members can perform domain controller administrator actions
on the VMware Directory Service
SSO Predefined Group: SolutionUsers
Each solution user authenticates individually to vCenter
Single Sign-On with a certificate. By default, VMCA provisions solution users
with certificates. Do not add members to this group explicitly
SSO Predefined Group: CAAdmins
Members have administrator privileges for VMCA. Adding members
to this group is not usually recommended, but a user must be a member
of this group to perform most certificate management operations, such as using
the certool command.
SSO Predefined Group: SystemConfiguration.BashShellAdministrators
Only applies to vCenter
Server appliance deployments. Members can enable and disable access to the
BASH Shell.
SSO Predefined Group: SystemConfiguration.Administrators
Members can view and manage the
system configuration and perform tasks such as restarting services.
SSO Predefined Group: LicenseSevice.Administrators
Members have full write access to all licensing-
related data and can add, remove, assign, and unassign serial keys for all
product assets registered in the licensing service.
SSO Predefined Group: Administrators
Members can perform SSO administration tasks for the VMware Directory Service (vmdir).

SSO Policies and Parameters - Password policy
Maximum lifetime: Maximum number of days that a password can exist before the user must change it.
Restrict reuse: Number of the user’s previous passwords that cannot be selected.
Maximum length: Maximum number of characters that are allowed in the password.
Minimum length: Minimum number of characters that are allowed in the password, which must be no less than the combined minimum of alphabetic, numeric, and special character requirements.
Character requirements: Minimum number of different character types that are required in the password. The types include special, alphabetic, uppercase, lowercase, and numeric.
Identical adjacent characters: The number of identical adjacent characters that are supported in a password. The value must be greater than 0.
SSO Policies and Parameters - Lockout policy
Max number of failed login attempts: Maximum number of failed login attempts that are allowed before the account is locked.
Time interval between failures: Time period in which failed login attempts must occur to trigger a lockout.
Unlock time: The amount of time the account stays locked. The value 0 specifies that an administrator must
explicitly unlock the account.
SSO Policies and Parameters - Token policy
Clock tolerance: Time difference in milliseconds that SSO tolerates between a client clock and a domain controller clock. If the time difference is greater than the specified value, SSO declares the token to be invalid.
Maximum token renewal count: Maximum number of times a token may be renewed before a new security token is required.
Maximum token delegation count: Maximum number of times a single holder-of-key token can be delegated.
Maximum bearer token lifetime: The lifetime value of a bearer token before the token has to be reissued.
Maximum holder-of-key token lifetime: The lifetime value of a holder-of-key token before the token is marked invalid.

Description: Host and target both support bidirectional CHAP.
Supported: Software iSCSI, Dependent hardware iSCSI
Claim rules can be created based on the following elements:
vendor string - A claim rule can be set up using the vendor string, which must be an exact match. An example would be vendor=DELL.
model string - A claim rule can be set up using the model string, which must be an exact match. An example would be model=Universal Xport.
transport type - A claim rule can be created to mask all LUNs based on the transport type. Valid transport types are block, fc, iscsi, iscsivendor, ide, sas, sata, usb, parallel, and unknown.
Driver type - A driver name can be used to create a claim rule. Figure 5-18 lists all the drivers that can be used in a claim rule. You can set up a claim rule masking all paths to devices attached to an HBA using a driver such as the iscsi_vmk driver
