ADmodcmd - CMD

Overview

The ADmodcmd command is a command-line utility designed to modify objects within an Active Directory (AD) environment. It allows administrators to make changes to user accounts, group memberships, and other directory attributes in a programmatic way. This tool is particularly effective in large-scale environments for automating bulk modifications and managing AD objects systematically.

Syntax

The basic syntax for using ADmodcmd is as follows:

ADmodcmd [options] <DN> <attributes>

Where:

<DN> specifies the Distinguished Name of the AD object to modify.
<attributes> are the attributes to modify in the form attr1=value1 attr2=value2…

Syntax Variations:

To modify a single attribute:

ADmodcmd -u <user> -p <password> <DN> <attribute>=<value>

For bulk modifications using a file:
```
ADmodcmd -f <filename>
```

Options/Flags

-u
Specifies the username for authentication. If omitted, the command will attempt to run with the current user permissions.

-p
The password for the account specified with -u. For safety, it is recommended to use this option in a secure manner.

-f
Allows for bulk modifications from a file containing a series of distinguished names (DNs) and attributes to modify.

-v
Enables verbose mode, providing detailed output about the command’s operation and the results.

-h
Displays help information about the command.

Default Values:

If no user and password are provided, the command will default to using the credentials of the current user session.

Examples

Modifying a Single Attribute:

ADmodcmd -u admin -p adminpass "CN=John Doe,OU=Users,DC=example,DC=com" description="New account description"

Bulk Modification Using a File:
```
ADmodcmd -f modifications.txt
```
Where modifications.txt contains multiple lines formatted as DN attribute=value.

Common Issues

Permission Issues: Users may encounter permission errors if the credentials provided do not have sufficient rights to modify AD objects. Ensure the account has the necessary privileges.
Syntax Errors: Incorrect format of DN or attributes can result in failures. Always check the syntax carefully before running the command.
Network Issues: Being a network-based command, issues like network timeouts or DNS failures can affect its operation. Verify network connectivity and settings.

Integration

ADmodcmd can be integrated with scripts to automate user management tasks. Here’s an example of a script that reads user data from a CSV file and updates AD accordingly:

for /f "tokens=1,2 delims=," %%i in (users.csv) do (
    ADmodcmd -u admin -p pass "CN=%%i,OU=Users,DC=example,DC=com" phoneNumber=%%j
)

dsquery – Finds objects in Active Directory.
dsmod – Modifies objects in Active Directory.
dsadd – Adds objects to Active Directory.
