Directory Services

Information Technology Services has two directory service offerings. Microsoft’s Active Directory is a centralized and standardized system for Microsoft Windows hosts that automates network management of user data, security, and distributed resources and enables inter-operation with other directories. The enterprise Active Directory is hosted and managed by Information Technology Services.

ITS also provides enterprise GAL (Lightweight Directory Access Protocol) services to enable the searching and browsing of directory information in its central information systems. The GAL service is used for authentication by many university information systems as well as for address look ups by some email clients and the online GC Faculty, Staff and Student directories.

GC Active Directory (GC AD)

Joining the GC Active Directory (GC AD) offers several advantages to system administrators and computer users. The GC AD is already integrated with campus infrastructure for DNS and GAL. GCAD provides support for a single sign-on environment with other Active Directory integrated services and improved security at the desktop level. Active Directory can also help system administrators with software distribution and easier control of Windows-based computers via Group Policy Objects. Using Active Directory, you can efficiently manage users, computers, groups, printers, applications, and other directory-enabled objects from one secure, centralized location.

Services Provided:

  • Support for the hardware, security, redundancy, and backup of the domain controller machines that run the GC AD forest
  • Delegated management for OU Administrators
  • Integration with the campus GAL directory service which automatically creates the accounts for faculty, and staff in GC AD
  • Integration with the campus GAL directory service which updates user attributes in the directory
  • Integration with the campus (BIND-based) DNS service
  • Easier computer resource management through Group Policy Objects (GPO), remote software installation (SMS), and the establishment of minimum security requirements.
  • Forum for discussion of Active Directory and Active Directory Security issues through an AD community group
  • Notice of important changes and scheduled maintenance through the AD Community contact list and the ITS Change List.
  • Support for development and distribution of utility and administrative scripts and a knowledge base to help administrators find a quick solution to common problems.
  • Support for user and machine certificates via the GC AD PKI service


  • A single, consistent point of management for users, applications, and devices.
  • Simplified management and use of file and print services making network resources easier to find, configure and use.
  • A central control of authentication information to manage security services for internal desktop users and remote users.
  • A single sign-on to active directory integrated network resources for users.

GC Active Directory (GC AD) account:

  • Active directory accounts will be created automatically. If your account is not present please fill out the form below.

The GAL (Global Address List) has two main uses. First, it can be queried for directory information (phone, email, etc.) for GC faculty, staff and students, either from the GC website or within your email client. It is also used for authentication by university information systems, including logging into Canvas, Webmail and many other central and departmental applications.

Instructions on how to configure your email client can be found by contacting the service desk.

LDAP Authentication

If you would like to set up your departmental application to authenticate users using username and password, please complete a Data Access Request and submit a case.
