From 766b534da0c3a1ed09fe187323eaae0440eb7784 Mon Sep 17 00:00:00 2001 From: Rob Crittenden Date: Mon, 7 Dec 2009 23:17:00 -0500 Subject: Make the IPA server host and its services "real" IPA entries We use kadmin.local to bootstrap the creation of the kerberos principals for the IPA server machine: host, HTTP and ldap. This works fine and has the side-effect of protecting the services from modification by an admin (which would likely break the server). Unfortunately this also means that the services can't be managed by useful utilities such as certmonger. So we have to create them as "real" services instead. --- ipaserver/install/krbinstance.py | 38 ++++++++++++++++++++++++++++++++++++++ 1 file changed, 38 insertions(+) (limited to 'ipaserver/install/krbinstance.py') diff --git a/ipaserver/install/krbinstance.py b/ipaserver/install/krbinstance.py index a33ab233..c4a20b54 100644 --- a/ipaserver/install/krbinstance.py +++ b/ipaserver/install/krbinstance.py @@ -32,6 +32,7 @@ from ipapython import sysrestore from ipapython import ipautil from ipalib import util from ipalib import errors +from ipalib import uuid from ipaserver import ipaldap @@ -91,6 +92,40 @@ class KrbInstance(service.Service): else: self.fstore = sysrestore.FileStore('/var/lib/ipa/sysrestore') + def move_service_to_host(self, principal): + """ + Used to move a host/ service principal created by kadmin.local from + cn=kerberos to reside under the host entry. + """ + conn = None + + service_dn = "krbprincipalname=%s,cn=%s,cn=kerberos,%s" % (principal, self.realm, self.suffix) + try: + conn = ipaldap.IPAdmin("127.0.0.1") + conn.simple_bind_s("cn=directory manager", self.admin_password) + except Exception, e: + logging.critical("Could not connect to the Directory Server on %s" % self.fqdn) + raise e + service_entry = conn.getEntry(service_dn, ldap.SCOPE_BASE) + conn.deleteEntry(service_dn) + + # Create a host entry for this master + host_dn = "fqdn=%s,cn=computers,cn=accounts,%s" % (self.fqdn, self.suffix) + host_entry = ipaldap.Entry(host_dn) + host_entry.setValues('objectclass', ['top', 'ipaobject', 'nshost', 'ipahost', 'pkiuser', 'krbprincipalaux', 'krbprincipal', 'krbticketpolicyaux']) + host_entry.setValue('krbextradata', service_entry.getValue('krbextradata')) + host_entry.setValue('krblastpwdchange', service_entry.getValue('krblastpwdchange')) + host_entry.setValue('krbpasswordexpiration', service_entry.getValue('krbpasswordexpiration')) + host_entry.setValue('krbprincipalname', service_entry.getValue('krbprincipalname')) + host_entry.setValue('krbticketflags', service_entry.getValue('krbticketflags')) + host_entry.setValue('krbprincipalkey', service_entry.getValue('krbprincipalkey')) + host_entry.setValue('serverhostname', self.fqdn.split('.',1)[0]) + host_entry.setValue('cn', self.fqdn) + host_entry.setValue('fqdn', self.fqdn) + host_entry.setValue('ipauniqueid', str(uuid.uuid1())) + conn.addEntry(host_entry) + conn.unbind() + def __common_setup(self, ds_user, realm_name, host_name, domain_name, admin_password): self.ds_user = ds_user self.fqdn = host_name @@ -404,6 +439,7 @@ class KrbInstance(service.Service): def __create_ds_keytab(self): ldap_principal = "ldap/" + self.fqdn + "@" + self.realm installutils.kadmin_addprinc(ldap_principal) + self.move_service(ldap_principal) self.fstore.backup_file("/etc/dirsrv/ds.keytab") installutils.create_keytab("/etc/dirsrv/ds.keytab", ldap_principal) @@ -424,6 +460,8 @@ class KrbInstance(service.Service): os.chown("/etc/krb5.keytab", 0, 0) os.chmod("/etc/krb5.keytab", 0600) + self.move_service_to_host(host_principal) + def __export_kadmin_changepw_keytab(self): installutils.kadmin_modprinc("kadmin/changepw", "+requires_preauth") -- cgit
