dsconfigad -show | awk '/Active Directory Domain/{print $NF}'

is that what you're looking for?

Hi Bernard,

You can achieve this with the following Extension Attribute script:

#!/bin/bash



#ping the Domain or DC

ping -c 3 -o <DC FQDN OR DOMAIN> 1> /dev/null 2> /dev/null



# If the ping was successful

if [[ $? == 0 ]]; then

    # Check the domain returned with dsconfigad

    domain=$( dsconfigad -show | awk '/Active Directory Domain/{print $NF}' )

    # If the domain is correct

    if [[ "$domain" == "<ACTIVE DIRECTORY DOMAIN HERE>" ]]; then

        # Check the id of a user

        id -u <DOMAIN USER ACCOUNT NAME>

        # If the check was successful...

        if [[ $? == 0 ]]; then

            echo "<result>Bound Correctly</result>"

        else

            # If the check failed

            echo "<result>Cannot communicate with AD</result>"

        fi

    else

        # If the domain returned did not match our expectations

        echo "<result>Incomplete bind</result>"

    fi

elif [[ $bftr == "Bound Correctly" ]]; then

    # We can't see the DCs, so no way to properly check

else

echo "<result>Not in range of a DC</result>"

fi



exit 0

Substituting correct values for <...>

This will try and ping either one of your DC's or the domain (which will ping the primary DC) if successful it will check the domain name the machine is bound to against what you specify as the correct domain and will also try and query the user object and if communicating with your AD correctly will return the groups the user object is a member of.

The command you are looking for is dsconfigad, rather than the ldap option. at its most basic "dsconfigad -show" will dump out the status of the AD plug-in. However to check the binding is actually working the easiest option is to run "id USERNAME" where USERNAME is a domain user without a local presence on the Mac.

Worth noting that if you just want to see which domain a computer is bound to, if at all, the JSS already uses dsconfigad every recon to populate this in the Operating System section of the Inventory tab in a computer record. You can use the Active Directory Status as a criterion in a Smart Group/Advanced Search.

All great answers, but since @Chris got in first, I'll give him the tick :)

Thanks a lot. It's working now. I've created the extension attribute.

I'm curious if anyone is using odutil

odutil show nodenames

Seems to work for me. Not sure if this is a new utility, but it seems to be inline with the green/red dots in System Preferences > Users and Groups.

@cddwyer I took your script there and extended it a bit because this AD binding bug is really ^&*%^( annoying. I have the script running on every check-in on computers that do not have Mobile Accounts enabled.

Here's my code: https://github.com/mstrperson/AppleADBindWorkAround

I Added an automatic rebind using an AD service account and email notifications using postfix!
