[Samba] Unable to net ads join samba to an active directory domain Failed to join domain: failed to connect to AD: Can't contact LDAP server
-----Original Message----- From: samba [mailto:samba-bounces at lists.samba.org] On Behalf Of Rowland Penny via samba Sent: Wednesday, November 17, 2021 1:57 AM To: sambalist Subject: Re: [Samba] Unable to net ads join samba to an active directory domain Failed to join domain: failed to connect to AD: Can't contact LDAP server On Tue, 2021-11-16 at 15:10 -0800, Michael Evans wrote:> What sections do you believe are missing, and how would those impact > joining > the active directory domain? > > Shares are missing, but none have been setup yet, that's a future me > problem.That wasn't your problem.> > ID mapping is based on RFC2307 and stored within the active > directory; is " > idmap config ad" sufficient for that task?

Is something like a firewall getting in the way ? Rowland Your Third point: If I DO need it then it isn't _optional_ and the documentation is incorrect / confusing. Still, which sections, what keywords should I be looking for, and more to the point, why aren't those in the Member Server documentation to begin with, without external references? Any inconsistencies at all. nslookup 10.2.0.35 35.0.2.10.in-addr.arpa name = ad-mo3.nc.nor-consult.com. I added the reverse DNS entries manually; they weren't even needed for the Win10 join to the domain. Does Samba perform a case-sensitive compare? The guide's example is DC1.realm (lowercase), and I only ever think of DNS entries as lowercased because that's the normal convention. Time synchronization; VM, sntp run daily by schedule. "If you need your users to have different login shells and/or Unix home directory paths, or you want them to have the same ID everywhere, you will need to use the winbind 'ad' backend and add RFC2307 attributes to AD." Yes, I need that, and have done that on the DC. Documentation error: Hyperlink is NOT default hyperlink colors and NOT underlined. idmap config ad <<< That looks like just text with emphasis, NOT a hyperlink. This table of 3 options should instead be broken out to small sections, each with a single (current version) template example and a link to the full set of directions. Ideally all three examples would fit on a typical PC screen when viewing the wiki. https://wiki.samba.org/index.php/Idmap_config_ad The Config AD Backend and NSS info sections should be in that order, not the NSS then AD order.
