92 is used to authenticate to the Kerberos server as
94 or if none is given, a system generated default (typically your login
95 name at the default realm), and acquire a ticket granting ticket that
96 can later be used to obtain tickets for other services.

104 Obtain a ticket than can be forwarded to another host.
105 .It Fl F Fl Fl no-forwardable
106 Do not obtain a forwardable ticket.

108 Don't ask for a password, but instead get the key from the specified
110 .It Fl l Ar time , Fl Fl lifetime= Ns Ar time
111 Specifies the lifetime of the ticket.
112 The argument can either be in seconds, or a more human readable string
115 .It Fl p , Fl Fl proxiable
116 Request tickets with the proxiable flag set.
117 .It Fl R , Fl Fl renew
119 The ticket must have the

125 with an infinite time.
126 .It Fl r Ar time , Fl Fl renewable-life= Ns Ar time
127 The max renewable ticket life.

129 Get a ticket for a service other than krbtgt/LOCAL.REALM.
130 .It Fl s Ar time , Fl Fl start-time= Ns Ar time
131 Obtain a ticket that starts to be valid
133 (which can really be a generic time specification, like
135 seconds into the future.
136 .It Fl k , Fl Fl use-keytab
139 but with the default keytab name (normally
140 .Ar FILE:/etc/krb5.keytab ) .
141 .It Fl v , Fl Fl validate
142 Try to validate an invalid ticket.
143 .It Fl e , Fl Fl enctypes= Ns Ar enctypes
144 Request tickets with this particular enctype.

146 read the password from the first line of
152 the password will be read from the standard input.
153 .It Fl Fl fcache-version= Ns Ar version-number
154 Create a credentials cache of version
156 .It Fl a , Fl Fl extra-addresses= Ns Ar enctypes
157 Adds a set of addresses that will, in addition to the systems local
158 addresses, be put in the ticket.
159 This can be useful if all addresses a client can use can't be
160 automatically figured out.
161 One such example is if the client is behind a firewall.
163 .Li libdefaults/extra_addresses
166 .It Fl A , Fl Fl no-addresses
167 Request a ticket with no addresses.
169 Request an anonymous ticket (which means that the ticket will be
170 issued to an anonymous principal, typically
171 .Dq anonymous@REALM ) .
173 Parse principal as a enterprise (KRB5-NT-ENTERPRISE) name. Enterprise
174 names are email like principals that are stored in the name part of
175 the principal, and since there are two @ characters the parser needs
176 to know that the first is not a realm.
177 An example of an enterprise name is
178 .Dq lha@e.kth.se@KTH.SE ,
179 and this option is usually used with canonicalize so that the
180 principal returned from the KDC will typically be the real principal
183 Gets AFS tickets, converts them to version 4 format, and stores them
185 Only useful if you have AFS.
194 options can be set to a default value from the
196 section in krb5.conf, see
197 .Xr krb5_appdefault 3 .
203 will set up new credentials caches, and AFS PAG, and then run the given
205 When it finishes the credentials will be removed.
209 Specifies the default credentials cache.
