You can disable all plugins and activate the AD plugin first, it should tell you if a php/linux package is missing (Worked for me)

Series of random thoughts…

1. Is the domain firewall off on windows
2. Is SELinux disabled
3. You can add port 389 to the linux firewall
4. Check with ADSIEdit if the account you are using to connect has read access to the windows domain root or the OUs

You can troubleshoot by first connecting to an OU, then if it works you add the whole domain.

2nd…Did you join the linux server to the Windows AD using realm join?

If you have a people’s OU…did you reference it in the Base DN with
base_dn = OU=People,DC=domain,DC=com,DC=pt

Also use the Domain Controller IP Address instead of dc2.domain.com

You can confirm if the user account you used in the Environment -> Verify Credentials section is within the OU in the Base DN section.
