Help Setting up FreePBX with AD user

I’m encountering a straightforward issue with my FreePBX installation. I successfully imported my Active Directory (AD) users, and everything appears to be in order except for one crucial aspect: none of them have extensions assigned. Is there a method to ensure that a user automatically receives an extension upon creation? Given that I have around 100 users, manually assigning extensions would be extremely tedious. Unfortunately, I haven’t been able to find a solution thus far. It seems that every piece of information is imported except for the extension field. If anyone could offer assistance, I would greatly appreciate it. Thank you.
