Domain Local Global Catalog

Because every domain controller stores the only domain directory partition in the forest configuring each domain controller as a global catalog server does not require any additional disk space usage cpu usage or replication traffic.

Domain local global catalog. As it uses only partial information and a set of attributes that are most commonly used for searching. A global catalog is a multi domain catalog that allows for faster searching of objects without the need for a domain name. You can assign additional domain controllers as gc by selecting the global catalog option in the active directory sites and services snap in. To make a domain controller a global catalog start by launching the active directory sites and services mmc snap in.

This post is regarding how to unhost and rehost the global partition for a domain controller. When a domain controller is selected to host the global catalog the kcc on the domain controller that is being promoted uses its discretion to build connection objects from. Better if you guys do the unhost and rehost for that partition in which. The recommendations in this section are based upon the following assumption in the hub and spoke topology.

The global catalog is a solution to the websphere application server limitation of a single registry. It is preferable that if all domain controllers and global catalogs in a satellite site become unavailable a client that s searching for a domain controller or global catalog in that site fails over to a domain controller or global catalog that s in a. Promoting a domain controller to be a global catalog is a simple change that initiates replication of the partial attribute set for each domain in the forest other than the domain controller s domain. Users from the local domain controller contain group memberof information.

There are limitations to the global catalog. A global catalog must replicate inbound copies of all objects from all domain partitions in the forest before the global catalog can advertise the global catalog role. You can use the global catalog on any domain controller in the forest even in subdomains. In a single domain forest configure all domain controllers as global catalog servers.

We can also do unhost and rehost by site and service but that do for all global catalog partitions. It can be done only if there are lingering objects exist in global partition.
