for authentication. Perhaps someone has a PAM module written that can re-write the principal name based either upon local rules or a series of LDAP lookups against Active Directory. Unfortunately, I am not aware of one.

Here are some detailed steps if it is not a simple configuration issue:The first step in troubleshooting a Key Distribution Center(KDC) connectivity problem while getting initial is to make sure that a KDC is being properly selected. There are two options: 1. If no KDC name is specified, the setup process will do a server(SRV) record lookup in domain name services(DNS) to find an authoritative KDC for the specified Realm. If the SRV record lookup fails, an error message will report that a KDC was not found. This method cannot be used if the SRV lookup will fail or if the lookup is likely to return a server which is not actually reachable. 2. If a KDC name is entered, no DNS SRV lookup will be done. Instead the fully qualified domain name(FQDN) will be constructed using that name as machine name and the Realm value as the DNS Domain. A normal lookup will then be done to resolve that FQDN to an Internet Protocol(IP) address. That lookup will be satisfied by a record in /etc/hosts or, if that does not return a result, by a DNS name resolution based on an A or C record. After either method of constructing the FQDN has been used and an IP address obtained, it is necessary that a connection to that KDC from the

I am following the official Ubuntu guide to set up a Kerberos client here: https://help.ubuntu.com/community/Samba/Kerberos, but I have encountered a problem when running the kinit command to connect to the domain server. The command I am running is: kinit Administrator@DS.DOMAIN.COM. This command returns the following error: Realm not local to KDC while getting initial credentials. Unfortunately, I cannot find any one else via Google searches that have experienced this exact error, so I have no idea what it means. The client is able to ping the server's hostname, so the DNS server is pointing to the domain server. Below is my krb5.conf file: [libdefaults] default = DS.DOMAIN.COM dns_lookup_realm = true dns_lookup_kdc true [realms] DS.DOMAIN.COM = { kdc = ds.domain.com:88 admin_server = ds.domain.com default_domain = domain.com } [domain_realm] .domain.com = DS.DOMAIN.COM domain.com = DS.DOMAIN.COM How can I correct these errors? I would greatly appreciate all help I can get! linux active-directory kerberos kinit share|improve this question edited Aug 3 '10 at 19:39 asked Aug 3 '10 at 19:04 Phanto 3762921 add a comment| 6 Answers 6 active oldest votes up vote 11 down vote accepted Is your domain name DS.DOMAIN.COM or just DOMAIN.COM ? In your realms you need to have them match, so assuming that DS.DOMAIN.COM is your domain you need to change: [domain_realm] .domain.com = DS.DOMAIN.COM domain.com = DS.DOMAIN.COM to [domain_realm] .ds.domain.com = DS.DOMAIN.COM ds.domain.com = DS.DOMAIN.COM However,
