From dadfbf9d153bcf8f7ce659981698ffa2292b3967 Mon Sep 17 00:00:00 2001 From: Alexander Bokovoy Date: Mon, 16 Jul 2012 13:12:42 +0300 Subject: [PATCH 32/79] Handle various forms of admin accounts when establishing trusts Realm administrator account may be specified using different form: Administrator, DOM\Administrator, Administrator@DOMAIN This patch introduces handling of the second two forms: - In DOM\Administrator only user name is used, short domain name is then taken from a discovered record from the AD DC - In Administrator@DOMAIN first DOMAIN is verified to be the same as the domain we are establishing trust to, and then user name is taken, together with short domain name taken from a discovered record from the AD DC Note that we do not support using to-be-trusted domain's trusted domains' accounts to establish trust as there is basically zero chance to verify that things will work with them. In addition, in order to establish trust one needs to belong to Enterprise Admins group in AD or have specially delegated permissions. These permissions are unlikely delegated to the ones in already trusted domain. https://fedorahosted.org/freeipa/ticket/2864 --- ipalib/plugins/trust.py | 8 ++++++++ ipaserver/dcerpc.py | 5 +++++ 2 files changed, 13 insertions(+) diff --git a/ipalib/plugins/trust.py b/ipalib/plugins/trust.py index 2932835e038d99d9c48f1822e76fbc2e1570f92f..792e6cac2a2f9ebb61f84cc74d01be325995863e 100644 --- a/ipalib/plugins/trust.py +++ b/ipalib/plugins/trust.py @@ -180,6 +180,14 @@ class trust_add(LDAPCreate): # generate random trustdom password to do work on both sides if 'realm_admin' in options: realm_admin = options['realm_admin'] + names = realm_admin.split('@') + if len(names) > 1: + # realm admin name is in UPN format, user@realm, check that + # realm is the same as the one that we are attempting to trust + if keys[-1].lower() != names[-1].lower(): + raise errors.ValidationError(name=_('AD Trust setup'), + error=_('Trusted domain and administrator account use different realms')) + realm_admin = names[0] if 'realm_passwd' not in options: raise errors.ValidationError(name=_('AD Trust setup'), error=_('Realm administrator password should be specified')) diff --git a/ipaserver/dcerpc.py b/ipaserver/dcerpc.py index 07e40c2d35b41a2665232f3e6d853b47aef707bb..6b830f65b854b74fcf080b071212e7658f334adf 100644 --- a/ipaserver/dcerpc.py +++ b/ipaserver/dcerpc.py @@ -363,6 +363,11 @@ class TrustDomainJoins(object): rd.read_only = True if realm_admin and realm_passwd: if 'name' in rd.info: + names = realm_admin.split('\\') + if len(names) > 1: + # realm admin is in DOMAIN\user format + # strip DOMAIN part as we'll enforce the one discovered + realm_admin = names[-1] auth_string = u"%s\%s%%%s" % (rd.info['name'], realm_admin, realm_passwd) td = get_instance(self) td.creds.parse_string(auth_string) -- 1.7.11.2
