How familiar are you with Active Directory?

Active Directory (AD) is a Microsoft directory service widely used for managing users, groups, computers, and security policies in corporate networks. In my experience, I have dealt with AD at the level of configuration and support: adding and removing users, managing security groups, configuring Group Policy Objects (GPO), and troubleshooting authentication and access issues.

For example, I often had to restore user access, reset passwords, and configure permissions to network resources through AD. I also have experience integrating applications with AD for single sign-on (SSO). Overall, working with Active Directory was a regular and sufficiently deep part of supporting infrastructure and solving typical user tasks.
