91 is used to authenticate to the Kerberos server as
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.
99 .It Fl c Ar cachename Fl -cache= Ns Ar cachename
100 The credentials cache to put the acquired ticket in, if other than
102 .It Fl f 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 -keytab= Ns Ar keytabname
106 Don't ask for a password, but instead get the key from the specified
108 .It Fl l Ar time , 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
113 .It Fl p , Fl -proxiable
114 Request tickets with the proxiable flag set.
117 The ticket must have the
119 flag set, and must not be expired.

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

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

152 Create a credentials cache of version
154 .It Fl a , 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.
161 .Li libdefaults/extra_addresses
164 .It Fl A , Fl -no-addresses
165 Request a ticket with no addresses.
167 Request an anonymous ticket (which means that the ticket will be
168 issued to an anonymous principal, typically
169 .Dq anonymous@REALM ) .
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
181 Gets AFS tickets, converts them to version 4 format, and stores them
183 Only useful if you have AFS.
192 options can be set to a default value from the
194 section in krb5.conf, see
195 .Xr krb5_appdefault 3 .
201 will set up new credentials caches, and AFS PAG, and then run the given
203 When it finishes the credentials will be removed.
207 Specifies the default credentials cache.
214 Specifies the Kerberos 4 ticket file to store version 4 tickets in.
