Both .B kadmin and .B kadmin.local provide identical functionalities; the difference is that .B kadmin.local runs on the master KDC if the database is db2 and does not use Kerberos to authenticate to the database. Except as explicitly noted otherwise, this man page will use .B kadmin to refer to both versions. .B kadmin provides for the maintenance of Kerberos principals, KADM5 policies, and service key tables (keytabs). .PP The remote version uses Kerberos authentication and an encrypted RPC, to operate securely from anywhere on the network. It authenticates to the KADM5 server using the service principal .IR kadmin/admin . If the credentials cache contains a ticket for the .I kadmin/admin principal, and the .B \-c .I credentials_cache option is specified, that ticket is used to authenticate to KADM5. Otherwise, the .B -p and .B -k options are used to specify the client Kerberos principal name used to authenticate. Once .B kadmin has determined the principal name, it requests a .I kadmin/admin Kerberos service ticket from the KDC, and uses that service ticket to authenticate to KADM5. .PP If the database is db2, the local client .BR kadmin.local , is intended to run directly on the master KDC without Kerberos authentication. The local version provides all of the functionality of the now obsolete .IR kdb5_edit (8), except for database dump and load, which is now provided by the .IR kdb5_util (8) utility. .PP If the database is LDAP, kadmin.local need not be run on the KDC. .PP kadmin.local can be configured to log updates for incremental database propagation. Incremental propagation allows slave KDC servers to receive principal and policy updates incrementally instead of receiving full dumps of the database. This facility can be enabled in the .I kdc.conf file with the .I iprop_enable option. See the .I kdc.conf documentation for other options for tuning incremental propagation parameters. .SH OPTIONS .TP \fB\-r\fP \fIrealm\fP Use .I realm as the default database realm. .TP \fB\-p\fP \fIprincipal\fP Use .I principal to authenticate. Otherwise, kadmin will append "/admin" to the primary principal name of the default ccache, the value of the .SM USER environment variable, or the username as obtained with getpwuid, in order of preference. .TP \fB\-k\fP Use a keytab to decrypt the KDC response instead of prompting for a password on the TTY. In this case, the default principal will be host/\fIhostname\fP. If there is not a keytab specified with the .B \-t option, then the default keytab will be used. .TP \fB\-t\fP \fIkeytab\fP Use .I keytab to decrypt the KDC response. This can only be used with the .B \-k option. \fB-n\fP Requests anonymous processing. Two types of anonymous principals are supported. For fully anonymous Kerberos, configure pkinit on the KDC and configure .I pkinit_anchors in the client's krb5.conf. Then use the .B -n option with a principal of the form .I @REALM (an empty principal name followed by the at-sign and a realm name). If permitted by the KDC, an anonymous ticket will be returned. A second form of anonymous tickets is supported; these realm-exposed tickets hide the identity of the client but not the client's realm. For this mode, use .B kinit -n with a normal principal name. If supported by the KDC, the principal (but not realm) will be replaced by the anonymous principal. As of release 1.8, the MIT Kerberos KDC only supports fully anonymous operation. .TP \fB\-c\fP \fIcredentials_cache\fP Use .I credentials_cache as the credentials cache. The .I credentials_cache should contain a service ticket for the .I kadmin/admin service; it can be acquired with the .IR kinit (1) program. If this option is not specified, .B kadmin requests a new service ticket from the KDC, and stores it in its own temporary ccache. .TP \fB\-w\fP \fIpassword\fP Use .I password instead of prompting for one on the TTY. Note: placing the password for a Kerberos principal with administration access into a shell script can be dangerous if unauthorized users gain read access to the script. .TP \fB\-q\fP \fIquery\fP pass .I query directly to .BR kadmin , which will perform .I query and then exit. This can be useful for writing scripts. .TP \fB\-d\fP \fIdbname\fP Specifies the name of the Kerberos database. This option does not apply to the LDAP database. .TP \fB\-s\fP \fIadmin_server[:port]\fP Specifies the admin server which kadmin should contact. .TP \fB\-m\fP Do not authenticate using a keytab. This option will cause kadmin to prompt for the master database password. .TP \fB\-e\fP \fIenc:salt_list\fP Sets the list of encryption types and salt types to be used for any new keys created. .TP .B \-O Force use of old AUTH_GSSAPI authentication flavor. .TP .B \-N Prevent fallback to AUTH_GSSAPI authentication flavor. .TP \fB\-x\fP \fIdb_args\fP Specifies the database specific arguments. Options supported for LDAP database are: .RS .TP \-x host= specifies the LDAP server to connect to by a LDAP URI. .TP \-x binddn= .fi specifies the DN of the object used by the administration server to bind to the LDAP server. This object should have the read and write rights on the realm container, principal container and the subtree that is referenced by the realm. .TP \-x bindpwd= .fi specifies the password for the above mentioned binddn. It is recommended not to use this option. Instead, the password can be stashed using the stashsrvpw command of kdb5_ldap_util. .RE .SH DATE FORMAT Various commands in kadmin can take a variety of date formats, specifying durations or absolute times. Examples of valid formats are: .sp .nf .RS 1 month ago 2 hours ago 400000 seconds ago last year this Monday next Monday yesterday tomorrow now second Monday a fortnight ago 3/31/92 10:00:07 PST January 23, 1987 10:05pm 22:00 GMT .RE .fi .PP Dates which do not have the "ago" specifier default to being absolute dates, unless they appear in a field where a duration is expected. In that case the time specifier will be interpreted as relative. Specifying "ago" in a duration may result in unexpected behavior. .PP .SH COMMANDS .TP \fBadd_principal\fP [\fIoptions\fP] \fInewprinc\fP creates the principal .IR newprinc , prompting twice for a password. If no policy is specified with the \-policy option, and the policy named "default" exists, then that policy is assigned to the principal; note that the assignment of the policy "default" only occurs automatically when a principal is first created, so the policy "default" must already exist for the assignment to occur. This assignment of "default" can be suppressed with the \-clearpolicy option. This command requires the .I add privilege. This command has the aliases .B addprinc and .BR ank . The options are: .RS .TP \fB\-x\fP \fIdb_princ_args\fP Denotes the database specific options. The options for LDAP database are: .RS .TP \-x dn= Specifies the LDAP object that will contain the Kerberos principal being created. .TP \-x linkdn= .fi Specifies the LDAP object to which the newly created Kerberos principal object will point to. .TP \-x containerdn= Specifies the container object under which the Kerberos principal is to be created. .TP \-x tktpolicy= Associates a ticket policy to the Kerberos principal. .RE .TP \fB\-expire\fP \fIexpdate\fP expiration date of the principal .TP \fB\-pwexpire\fP \fIpwexpdate\fP password expiration date .TP \fB\-maxlife\fP \fImaxlife\fP maximum ticket life for the principal .TP \fB\-maxrenewlife\fP \fImaxrenewlife\fP maximum renewable life of tickets for the principal .TP \fB\-kvno\fP \fIkvno\fP explicity set the key version number. .TP \fB\-policy\fP \fIpolicy\fP policy used by this principal. If no policy is supplied, then if the policy "default" exists and the -clearpolicy is not also specified, then the policy "default" is used; otherwise, the principal will have no policy, and a warning message will be printed. .TP \fB\-clearpolicy\fP .B -clearpolicy prevents the policy "default" from being assigned when .B -policy is not specified. This option has no effect if the policy "default" does not exist. .TP {\fB\-\fP|\fB+\fP}\fBallow_postdated\fP .B -allow_postdated prohibits this principal from obtaining postdated tickets. (Sets the .SM KRB5_KDB_DISALLOW_POSTDATED flag.) .B +allow_postdated clears this flag. .TP {\fB\-\fP|\fB+\fP}\fBallow_forwardable\fP .B -allow_forwardable prohibits this principal from obtaining forwardable tickets. (Sets the .SM KRB5_KDB_DISALLOW_FORWARDABLE flag.) .B +allow_forwardable clears this flag. .TP {\fB\-\fP|\fB+\fP}\fBallow_renewable\fP .B -allow_renewable prohibits this principal from obtaining renewable tickets. (Sets the .SM KRB5_KDB_DISALLOW_RENEWABLE flag.) .B +allow_renewable clears this flag. .TP {\fB\-\fP|\fB+\fP}\fBallow_proxiable\fP .B -allow_proxiable prohibits this principal from obtaining proxiable tickets. (Sets the .SM KRB5_KDB_DISALLOW_PROXIABLE flag.) .B +allow_proxiable clears this flag. .TP {\fB\-\fP|\fB+\fP}\fBallow_dup_skey\fP .B -allow_dup_skey Disables user-to-user authentication for this principal by prohibiting this principal from obtaining a session key for another user. (Sets the .SM KRB5_KDB_DISALLOW_DUP_SKEY flag.) .B +allow_dup_skey clears this flag. .TP {\fB\-\fP|\fB+\fP}\fBrequires_preauth\fP .B +requires_preauth requires this principal to preauthenticate before being allowed to kinit. (Sets the .SM KRB5_KDB_REQUIRES_PRE_AUTH flag.) .B -requires_preauth clears this flag. .TP {\fB\-\fP|\fB+\fP}\fBrequires_hwauth\fP .B +requires_hwauth requires this principal to preauthenticate using a hardware device before being allowed to kinit. (Sets the .SM KRB5_KDB_REQUIRES_HW_AUTH flag.) .B -requires_hwauth clears this flag. .TP {\fB\-\fP|\fB+\fP}\fBok_as_delegate\fP .B +ok_as_delegate sets the OK-AS-DELEGATE flag on tickets issued for use with this principal as the service, which clients may use as a hint that credentials can and should be delegated when authenticating to the service. (Sets the .SM KRB5_KDB_OK_AS_DELEGATE flag.) .B -ok_as_delegate clears this flag. .TP {\fB\-\fP|\fB+\fP}\fBallow_svr\fP .B -allow_svr prohibits the issuance of service tickets for this principal. (Sets the .SM KRB5_KDB_DISALLOW_SVR flag.) .B +allow_svr clears this flag. .TP {\fB\-\fP|\fB+\fP}\fBallow_tgs_req\fP .B \-allow_tgs_req specifies that a Ticket-Granting Service (TGS) request for a service ticket for this principal is not permitted. This option is useless for most things. .B +allow_tgs_req clears this flag. The default is .BR +allow_tgs_req . In effect, .B \-allow_tgs_req sets the .SM KRB5_KDB_DISALLOW_TGT_BASED flag on the principal in the database. .TP {\fB\-\fP|\fB+\fP}\fBallow_tix\fP .B \-allow_tix forbids the issuance of any tickets for this principal. .B +allow_tix clears this flag. The default is .BR +allow_tix . In effect, .B \-allow_tix sets the .SM KRB5_KDB_DISALLOW_ALL_TIX flag on the principal in the database. .TP {\fB\-\fP|\fB+\fP}\fBneedchange\fP .B +needchange sets a flag in attributes field to force a password change; .B \-needchange clears it. The default is .BR \-needchange . In effect, .B +needchange sets the .SM KRB5_KDB_REQUIRES_PWCHANGE flag on the principal in the database. .TP {\fB\-\fP|\fB+\fP}\fBpassword_changing_service\fP .B +password_changing_service sets a flag in the attributes field marking this as a password change service principal (useless for most things). .B \-password_changing_service clears the flag. This flag intentionally has a long name. The default is .BR \-password_changing_service . In effect, .B +password_changing_service sets the .SM KRB5_KDB_PWCHANGE_SERVICE flag on the principal in the database. .TP .B \-randkey sets the key of the principal to a random value .TP \fB\-pw\fP \fIpassword\fP sets the key of the principal to the specified string and does not prompt for a password. Note: using this option in a shell script can be dangerous if unauthorized users gain read access to the script. .TP \fB\-e\fP \fI"enc:salt ..."\fP uses the specified list of enctype\-salttype pairs for setting the key of the principal. The quotes are necessary if there are multiple enctype\-salttype pairs. This will not function against kadmin daemons earlier than krb5\-1.2. .nf .TP EXAMPLE: kadmin: addprinc tlyu/admin WARNING: no policy specified for "tlyu/admin@BLEEP.COM"; defaulting to no policy.
