Universal group membership.
Makes it possible to sign into 80 days without contact contacting a global catalog.
After this option is enabled and a user attempts to sign in for the first time universal group membership
is cached on non global catalog domain controllers.
After this information is obtained from a global catalog it is cached on the site's domain controller
indefinitely but is updated periodically by default updates secure every eight hours enabling this feature
results and foster sign in Times for users in remote sites without global catalogues because of the
authenticate and domain controllers do not have to access a global catalog.
Organizations may choose to use universal group membership caption for sites in which they do not want
to deploy a global catalog server.
I'd like to mention that replication has improved over the years and that the best practice recommendation
for most scenarios is to have a global catalog on every domain controller.
One historical concern was global catalogs.
Was this schema update in Windows 2000 Server which would trigger global catalog re initialization.
No.
Universal group membership caption can be a security risk when an administrator relies on removing a
server from a group universal group membership passion does not update with the application and the
user has up to eight hours of access even more when the wide area network link becomes so fly.
This cache and method is also somewhat unpredictable When users sign name the first time at a remote
site and the global catalog is not available.
The behavior is different from users who signed in previously.
Therefore because of these issues it is not typically recommended to use universal group membership.
So this will be an issue that you might need to address when you configure a tedious replication is
whether to deploy a global catalog servers in each site global catalog servers are required when users
sign into the domain.
So deploying a global catalog server in each site optimizes the user experience.
However if you deploy a global catalog server in inside.
Additional replication traffic might a cure that could be an issue if the network connection between
a tedious sites has limited bandwidth and there are other domains with a large number of objects in
the forest.
In these scenarios you can deploy domain controllers that Iran and Windows Server 2008 8 or newer and
then enable universal group membership caption for this for this site a domain controller in a site
that has enabled universal group membership cache in stores.
The universal group information locally after a user attempts to sign in for the first time the Domain
Controller obtains the user as universal group membership information from a global catalogue server
in another site.
It then caches the information indefinitely and refreshes it periodically.
The next time the user tries to sign in the Domain Controller obtains the universal group membership
information from its local cache without contacting a global catalogue server.
As I've said by default the universal group membership information in each domain controllers cache
refreshes every eight hours to refresh the cache domain controllers Santa universal group membership
confirmation request to designated global catalogue server you can configure universal group membership
caption from the anti DNS site settings node sadness.
