[Samba] samba on solaris 11 can not longer join Windows AD domain
I would like to move my Samba file server (Samba 4.4.14 on Solaris 11) from a classic domain into an Active Directory domain. The active directory domain has one Win 2008 directory server / domain controller, and one Win 2012 R2 DS. E-mail, among other things, depends on a Microsoft AD backend. A few months ago I was able to join a test server to the AD domain. Today I tried joining a 2nd one, but without success. testmachine1# net ads join -U Administrator at mydomain.com Enter Administrator at mydomain.com's password: Failed to join domain: Failed to set machine spn: Time limit exceeded Do you have sufficient permissions to create machine accounts? I thought that I may have not properly replicated the configuration, so I tried it on the first test server, with the same error. The event log on the AD DS shows Log Name: System Source: Microsoft-Windows-Security-Kerberos Date: 9/18/2017 10:01:27 PM Event ID: 3 Task Category: None Level: Error Keywords: Classic User: N/A Computer: DS1.mydomain.com Description: A Kerberos Error Message was received: on logon session Client Time: Server Time: 2:1:27.0000 9/19/2017 Z Error Code: 0xd KDC_ERR_BADOPTION Extended Error: 0xc00000bb KLIN(0) Client Realm: Client Name: Server Realm: MYDOMAIN.COM Server Name: DS1.mydomain.com Target Name: DS1.mydomain.com at MYDOMAIN.COM <mailto:DS1.mydomain.com at MYDOMAIN.COM> I have applied patches over the last few months to the Windows servers.

There is a distinct lack of 'idmap config' lines. Does the /etc/resolv.conf point to a DC as a nameserver ? Does the proposed Unix domain member get its IP via DHCP ? What is in /etc/hosts ? What is in /etc/krb5.conf ? Rowland

I think I hit paste twice. The problem with showing just the config file is that options not explicitly set may have different defaults depending on version. I have attached part of cat smb.conf below. /etc/hosts does not include the AD Domain controllers. /etc/resolv.conf shows 2ndary DNS servers, which in turn sync data from the AD Domain controllers. I don't think this is a DNS issue since "net join" and "net ads join" are locating the AD domain controllers. /etc/krb5/krb5.conf is set up for the MYDOMAIN realm. I can use the ldapclient and kinit to join the machine to the MYDOMAIN AD realm for "Unix" level user and group lookups (via ldap) and kerberos authentication. I did find that Solaris "native" kerberos and Samba expect krb5.keytab files in different locations , which I resolved with a sym link between /etc/krb5.keytab and /etc/krb5/krb5.keytab. All member servers use static IP.
