[\-\-help] [\-\-manual] [\-\-debug]
.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
This script is a wrapper around msktutil and ldapsearch to simplify
the creation of host and service keytabs.  The script is useful for
boot strapping the Kerberos credentials required to use Active
Directory as a backend keytab store for wallet.  The script shares
the wallet configuration file.
.PP
Generally, two keytabs will need to be created to setup wallet.  One
host keytab for the wallet server host and one service keytab for
wallet to use when connecting to an Active Directory Domain
Controller.
.PP
Note, this script does not update the Wallet database which means
any keytabs created by it will be invisible from wallet.
.SH "ACTIONS"
.IX Header "ACTIONS"
.IP "create" 4
.IX Item "create"
Add a keytab to \s-1AD\s0 and update the keytab file.  Fails if the keytab
already exists.
.IP "update" 4
.IX Item "update"
Update an existing keytab in \s-1AD\s0 and update the keytab file.  Fails if
the keytab does not exist.
.IP "delete" 4
.IX Item "delete"
Delete a keytab from \s-1AD\s0 and remove it from the keytab file.
.IP "show" 4
.IX Item "show"
Show \s-1AD\s0's view of the account corresponding to the keytab.  This action
does not use msktutil and queries \s-1AD\s0 directly using \s-1LDAP.\s0
.SH "OPTIONS AND ARGUMENTS"
.IX Header "OPTIONS AND ARGUMENTS"
.IP "keytab-id" 4
.IX Item "keytab-id"
This is either host principal name of the form host/<fqdn> or a
service principal name of the form service/<id>.  Service keytab
identifiers cannot be longer than 18 characters because of an
Active Directory restriction.
.IP "keytab-filename" 4
.IX Item "keytab-filename"
The name of the keytab file.  Defaults to /etc/krb5.keytab.
.IP "\-\-conf=filename" 4
.IX Item "--conf=filename"
The configuration file to read.  The script searches for a configuration
file in the following order.
.Sp
.Vb 4
\&      * The command line switch \-\-conf
\&      * The environment variable ADKEYTAB
\&      * The file .ad\-keytab.conf
\&      * The file /etc/ad\-keytab.conf
.Ve
.IP "\-\-ad_server=hostname" 4
.IX Item "--ad_server=hostname"
The name of the Active Directory host to connect to.  It is important
what the script contact only _one_ server due to the fact that
propagation within an Active Directory domain can be quite slow.
.IP "\-\-base_dn=ou=org,dc=domain,dc=tld" 4
.IX Item "--base_dn=ou=org,dc=domain,dc=tld"
The base distinguished name holding both computer and user accounts.
.IP "\-\-computer_rdn=dn" 4
.IX Item "--computer_rdn=dn"
The relative distinguished name to use as the base \s-1DN\s0 for both the
creation of host keytabs and searches of Active Directory.  The
distinguished name formed will be computer_rdn,base_dn.
.IP "\-\-user_rdn=dn" 4
.IX Item "--user_rdn=dn"
The relative distinguished name to use as the base \s-1DN\s0 for \s-1LDAP\s0
searches of Active Directory for service keytabs.  The distinguished
name formed will be user_rdn_rdn,base_dn.
.IP "\-\-dump" 4
.IX Item "--dump"
When displaying keytab attributes show all of the attributes.
.IP "\-\-help" 4
.IX Item "--help"
Displays help text.
.IP "\-\-manual" 4
.IX Item "--manual"
Displays more complete help text.
.IP "\-\-debug" 4
.IX Item "--debug"
Turns on debugging displays.
