# Connect to the Active Directory domain
pyad.set_defaults(ldap_server="<your_ldap_server>")

Replace <your_ldap_server> with the hostname or IP address of your domain controller.

Creating a New User Account:

Creating new user accounts is a common AD administration task. Here’s how you can do it with Python:

from pyad import *
 
# Set the organizational unit (OU) where the new user will be created
ou = pyad.adcontainer.ADContainer.from_dn("OU=Users,DC=example,DC=com")
 
# Create a new user object
new_user = pyad.aduser.ADUser.create("JohnDoe", ou)
 
# Set user attributes
new_user.update_attribute("givenName", "John")
new_user.update_attribute("sn", "Doe")
new_user.update_attribute("userPrincipalName", "JohnDoe@example.com")
new_user.update_attribute("password", "P@ssw0rd")
new_user.update_attribute("description", "Example User Account")
 
# Save changes
new_user.commit_changes()

Replace "OU=Users,DC=example,DC=com" with the distinguished name (DN) of the OU where you want to create the user.

Modifying User Attributes:

You can also modify existing user attributes using Python. Here’s an example of updating a user’s email address:

from pyad import *
 
# Retrieve the user object
user = pyad.aduser.ADUser.from_cn("JohnDoe")
 
# Update the email address
user.update_attribute("mail", "john.doe@example.com")
 
# Save changes
user.commit_changes()

Replace "JohnDoe" with the common name (CN) of the user you want to modify.

Deleting a User Account:

When a user leaves the organization or their account becomes obsolete, you may need to delete it from AD. Here’s how you can do it with Python:

from pyad import *
 
# Retrieve the user object
user = pyad.aduser.ADUser.from_cn("JohnDoe")
 
# Delete the user account
user.delete()

Replace "JohnDoe" with the CN of the user you want to delete.

Conclusion

Automating Active Directory administration with Python can greatly streamline repetitive tasks and improve efficiency in managing user accounts and other AD objects. By leveraging the pyad library, you can perform basic AD operations programmatically, saving time and reducing the risk of manual errors.
