sso_util — Kerberos — Open Directory Single Sign On

sso_util command [-args]

sso_util is a tool for setting up, interrogating and removing Kerberos configurations within the Apple Single Sign On environment. This tool can configure services, create and consume encrypted config records and tear down Kerberos installations

Commands for sso_util :

info [-p] [-g | -l | -L | -r dir_node_path [dir_node_path]]
Returns information about the current Single Sign On environment

info command arguments:

Returns the data in XML format
Returns the default Kerberos realm name
Returns a list of the services sso_util knows how to Kerberize
Returns the default Kerberos log file paths
dir_node_path
Returns whether or not the given node has a Kerberos record associated with it. If it does, it returns the default realm name. If dir_node_path is '.' (default) it also returns all the realm names available on the search path
dir_node_path
specifies the directory node in which to search for the computer record
configure -r REALM -a admin_name [-p password] service
Configures Kerberized services on the local machine for the given realm

configure command arguments:

REALM
Kerberos realm for the service principals
admin_name
Account name of an administrator authorized to make changes in the Kerberos database
password
Password for the above administrator. The password can also be stored in a file and the path to the file can be passed as an environment variable - SSO_PASSWD_PATH.
service
Service can be any number of afp, ftp, imap, pop, smtp, ssh, fcsvr, DNS, or all
useconfig [-u] [-R record_name] [-f dir_node_path] -a admin_name [-p password]
Uses a secure config record to configure a server for Kerberos

configure command arguments:

Forces the update, ignoring that the update may already have been installed
record_name
Name of the Computer record containing the secure config record
dir_node_path
Specifies the directory node in which to find the given computer record
admin_name
Account name of an user authorized to use the secure config record (see generateconfig)
password
Password for the above user. The password can also be stored in a file and the path to the file can be passed as an environment variable - SSO_PASSWD_PATH.

To configure a server in realm FOO.COM when you have the Kerberos administrator's password. Store the password in a file and set env var SSO_PASSWD_PATH to the file path

sso_util configure -r FOO.COM -a kerberos_admin all

To create a secure config record to allow the delegated administrators, Fred and Barney, to configure a server named fred.foo.com in realm FOO.COM (using an existing computer record). The Open Directory Master for foo.com is odmaster.foo.com. This can be run on any server and neither Fred nor Barney need to have the Kerberos administrator's password. Store the password in a file and set env var SSO_PASSWD_PATH to the file path.

sso_util generateconfig -r FOO.COM -R fred.foo.com -f /LDAPv3/odmaster.foo.com -U Fred,Barney -a kerberos_admin all

To use the secure config record to allow Barney to configure the server named fred.foo.com. Store the password in a file and set env var SSO_PASSWD_PATH to the file path.

sso_util useconfig -R fred.foo.com -f /LDAPv3/odmaster.foo.com -a Barney

/etc/krb5.keytab
The configure and useconfig commands create or modify the krb5.keytab file.

You can add -v debug_level to any of the sso_util commands. Debug level 1 provides status information, higher levels add progressively more levels of detail. The maximum is level 7.

The sso_util tool is used by the Apple Single Sign On system to set up Kerberized services integrated with the rest of the Single Sign On components.
