The best way to modify bulk groups quickly is by importing a CSV file which contains the attributes of the groups that need to be modified. This saves a lot of time as it becomes tedious for administrators if they have to modify every group individually.
First, create CSV file which contains the new values of the attributes of groups that need to replace the existing values. Then, import this CSV file and click on Apply. This will replace the existing values of the attributes of groups.
Click AD Mgmt - -> Group Management - -> Modify Groups using CSV
From the drop down menu, select the domain in which the Group (to be modified) is located
Import the CSV file which contains the necessary attributes to be modified and click Next
Use the check box to select the groups to be modified and click Update in AD.
Now, choose the attributes that need to be modified. Then, select the attribute based on which you want to query the attribute.
