This PowerShell script provides a graphical user interface (GUI) for managing Active Directory group memberships. It allows administrators to add users to groups temporarily, with an automatic scheduled task to remove them at a specified date and time.

• Search and select groups: Search for Active Directory groups by name.
• Search and select users: Search for users by username (SamAccountName) and select them for addition to a group.
• Temporary group membership: Add a user to a group temporarily, with an automatic removal at a specified end date and time.
• Scheduled task creation: The script creates a scheduled task that will remove the user from the group at the set time.
• PowerShell script: The script is written in PowerShell, leveraging the ActiveDirectory module for interacting with AD.

• Windows Server or Windows 10/11 with Active Directory module installed.
• PowerShell 5.1 or higher.
• Administrative privileges to interact with Active Directory.

1. Open the GroupMembershipManager.ps1 script in your PowerShell environment.
2. Run the script with administrator privileges.

1. Search for a Group: Enter a search term in the "Search Group" box and click Search. The groups that match the search term will be displayed in the "Select Group" dropdown.

2. Search for Users: Enter a search term in the "Search Users" box and click Search. Users matching the search term will be displayed in the "Select Users" dropdown. You can add users to a selected group temporarily.

3. Set the End Date & Time: Choose the end date and time when the user should be removed from the group using the DateTime picker.

4. Add User Temporarily: After selecting the group and user, click Add User Temporarily. This will add the user to the group and schedule a task to remove them at the specified end date and time.

5. Close the Application: If you wish to exit, click Close.

After selecting a group, a user, and setting an end date/time, the script will automatically:

• Add the user to the selected group.
• Schedule a task to remove the user at the specified end date/time.

The script will show error messages for the following scenarios:

• No search term entered.
• Group or user not selected.
• User already a member of the selected group.
• Errors when scheduling the task or modifying group memberships.
