 | 
|---|
| 90 | .Nm
 | 
|---|
| 91 | is used to authenticate to the Kerberos server as
 | 
|---|
| 92 | .Ar principal ,
 | 
|---|
| 93 | or if none is given, a system generated default (typically your login
 | 
|---|
| 94 | name at the default realm), and acquire a ticket granting ticket that
 | 
|---|
| 95 | can later be used to obtain tickets for other services.
 | 
|---|
| 96 | .Pp
 | 
|---|
| 97 | Supported options:
 | 
|---|
| 98 | .Bl -tag -width Ds
 | 
|---|
| 99 | .It Fl c Ar cachename Fl Fl cache= Ns Ar cachename
 | 
|---|
| 100 | The credentials cache to put the acquired ticket in, if other than
 | 
|---|
| 101 | default.
 | 
|---|
| 102 | .It Fl f Fl Fl no-forwardable
 | 
|---|
| 103 | Get ticket that can be forwarded to another host, or if the negative
 | 
|---|
| 104 | flags use, don't get a forwardable flag.
 | 
|---|
| 105 | .It Fl t Ar keytabname , Fl Fl keytab= Ns Ar keytabname
 | 
|---|
| 106 | Don't ask for a password, but instead get the key from the specified
 | 
|---|
| 107 | keytab.
 | 
|---|
| 108 | .It Fl l Ar time , Fl Fl lifetime= Ns Ar time
 | 
|---|
| 109 | Specifies the lifetime of the ticket.
 | 
|---|
| 110 | The argument can either be in seconds, or a more human readable string
 | 
|---|
| 111 | like
 | 
|---|
| 112 | .Sq 1h .
 | 
|---|
| 113 | .It Fl p , Fl Fl proxiable
 | 
|---|
| 114 | Request tickets with the proxiable flag set.
 | 
|---|
| 115 | .It Fl R , Fl Fl renew
 | 
|---|
| 116 | Try to renew ticket.
 | 
|---|
| 117 | The ticket must have the
 | 
|---|
| 118 | .Sq renewable
 | 
|---|
| 119 | flag set, and must not be expired.
 | 
|---|
| 120 | .It Fl Fl renewable
 | 
|---|
| 121 | The same as
 | 
|---|
| 122 | .Fl Fl renewable-life ,
 | 
|---|
| 123 | with an infinite time.
 | 
|---|
| 124 | .It Fl r Ar time , Fl Fl renewable-life= Ns Ar time
 | 
|---|
| 125 | The max renewable ticket life.
 | 
|---|
| 126 | .It Fl S Ar principal , Fl Fl server= Ns Ar principal
 | 
|---|
| 127 | Get a ticket for a service other than krbtgt/LOCAL.REALM.
 | 
|---|
| 128 | .It Fl s Ar time , Fl Fl start-time= Ns Ar time
 | 
|---|
| 129 | Obtain a ticket that starts to be valid
 | 
|---|
| 130 | .Ar time
 | 
|---|
| 131 | (which can really be a generic time specification, like
 | 
|---|
| 132 | .Sq 1h )
 | 
|---|
| 133 | seconds into the future.
 | 
|---|
| 134 | .It Fl k , Fl Fl use-keytab
 | 
|---|
| 135 | The same as
 | 
|---|
| 136 | .Fl Fl keytab ,
 | 
|---|
| 137 | but with the default keytab name (normally
 | 
|---|
| 138 | .Ar FILE:/etc/krb5.keytab ) .
 | 
|---|
| 139 | .It Fl v , Fl Fl validate
 | 
|---|
| 140 | Try to validate an invalid ticket.
 | 
|---|
| 141 | .It Fl e , Fl Fl enctypes= Ns Ar enctypes
 | 
|---|
| 142 | Request tickets with this particular enctype.
 | 
|---|
| 143 | .It Fl Fl password-file= Ns Ar filename
 | 
|---|
| 144 | read the password from the first line of
 | 
|---|
| 145 | .Ar filename .
 | 
|---|
| 146 | If the
 | 
|---|
| 147 | .Ar filename
 | 
|---|
| 148 | is
 | 
|---|
| 149 | .Ar STDIN ,
 | 
|---|
| 150 | the password will be read from the standard input.
 | 
|---|
| 151 | .It Fl Fl fcache-version= Ns Ar version-number
 | 
|---|
| 152 | Create a credentials cache of version
 | 
|---|
| 153 | .Ar version-number .
 | 
|---|
| 154 | .It Fl a , Fl Fl extra-addresses= Ns Ar enctypes
 | 
|---|
| 155 | Adds a set of addresses that will, in addition to the systems local
 | 
|---|
| 156 | addresses, be put in the ticket.
 | 
|---|
| 157 | This can be useful if all addresses a client can use can't be
 | 
|---|
| 158 | automatically figured out.
 | 
|---|
| 159 | One such example is if the client is behind a firewall.
 | 
|---|
| 160 | Also settable via
 | 
|---|
| 161 | .Li libdefaults/extra_addresses
 | 
|---|
| 162 | in
 | 
|---|
| 163 | .Xr krb5.conf 5 .
 | 
|---|
| 164 | .It Fl A , Fl Fl no-addresses
 | 
|---|
| 165 | Request a ticket with no addresses.
 | 
|---|
| 166 | .It Fl Fl anonymous
 | 
|---|
| 167 | Request an anonymous ticket (which means that the ticket will be
 | 
|---|
| 168 | issued to an anonymous principal, typically
 | 
|---|
| 169 | .Dq anonymous@REALM ) .
 | 
|---|
| 170 | .It Fl Fl enterprise
 | 
|---|
| 171 | Parse principal as a enterprise (KRB5-NT-ENTERPRISE) name. Enterprise
 | 
|---|
| 172 | names are email like principals that are stored in the name part of
 | 
|---|
| 173 | the principal, and since there are two @ characters the parser needs
 | 
|---|
| 174 | to know that the first is not a realm.
 | 
|---|
| 175 | An example of an enterprise name is
 | 
|---|
| 176 | .Dq lha@e.kth.se@KTH.SE ,
 | 
|---|
| 177 | and this option is usually used with canonicalize so that the
 | 
|---|
| 178 | principal returned from the KDC will typically be the real principal
 | 
|---|
| 179 | name.
 | 
|---|
| 180 | .It Fl Fl afslog
 | 
|---|
| 181 | Gets AFS tickets, converts them to version 4 format, and stores them
 | 
|---|
| 182 | in the kernel.
 | 
|---|
| 183 | Only useful if you have AFS.
