Full disclosure: I'm not an AD guy so this might pertain to something obvious. I apologize in advance if that's the case - I did try searching for prior questions regarding this.
I'm installing a Linux-based web application server in an AD environment (vanilla CentOS 5.x - no special integration with AD). The app performs LDAPS queries against Global Catalog servers. In order to discover which AD server to talk to, it performs a DNS Lookup for A records pertaining to the AD domain (foo.int). This specific query appears to be failing (I'm still looking into it).
In the meantime though, I'd like to confirm a few things:
- If I'm pointing the Linux server to Microsoft DNS servers, and query for the AD domain (foot.in), is it reasonable to assume that I should get A records pointing to some GCs?
- Is the availability of A records for GCs something that is pretty standard? Or is this something that varies from environment to environment? In other words, are there some environments that just don't have internal A records published at all for DCs?
- Are these specific records something that is automatically managed/updated, or are they manually added/edited by admins?
