Using a Login Service

Basic Operations
If SDL or SSO is set as the login service, a drop-down list that contains a list of users who have
previously logged on the system can be displayed.
If SSO is set as a login service, the DNS domain name is also displayed.
IMPORTANT
• To use SSO, SA (Security Agent) is required.
• DNS domain names are fixed (displayed only), therefore you cannot enter them.
• If you are using Windows 2000 SP4 or earlier, and there is more than a 30 minute time difference
between the current time set in the computer's registry using Windows Active Directory and the
time set on the machine, an error occurs when you log on using SSO. To be able to log on using
SSO, the current time on both the computer and the machine must match. For instructions on
setting the current date and time of the machine, see "Current Data and Time," on p. 6-29.
• You must enter a user's login name that has been preregistered in Windows Active Directory to
enter a user name for SSO authentication.
• You must use only alphanumeric characters, . (period), - (hyphen), and _(underscore) to enter a
user name for SSO authentication.
