19 kinit is used to authenticate to the Kerberos server as principal, or if
20 none is given, a system generated default (typically your login name at
21 the default realm), and acquire a ticket granting ticket that can later
22 be used to obtain tickets for other services.
23 Supported options:
25 -c cachename --cache=cachename
27 The credentials cache to put the acquired ticket in, if other
28 than default.
29 -f --forwardable
31 Obtain a ticket than can be forwarded to another host.
32 -F --no-forwardable
34 Do not obtain a forwardable ticket.
35 -t keytabname, --keytab=keytabname
37 Don't ask for a password, but instead get the key from the speci‐
38 fied keytab.
39 -l time, --lifetime=time
41 Specifies the lifetime of the ticket. The argument can either be
42 in seconds, or a more human readable string like ‘1h’.
43 -p, --proxiable
45 Request tickets with the proxiable flag set.
46 -R, --renew
48 Try to renew ticket. The ticket must have the ‘renewable’ flag
49 set, and must not be expired.
50 --renewable
52 The same as --renewable-life, with an infinite time.
53 -r time, --renewable-life=time
55 The max renewable ticket life.
56 -S principal, --server=principal
58 Get a ticket for a service other than krbtgt/LOCAL.REALM.
59 -s time, --start-time=time
61 Obtain a ticket that starts to be valid time (which can really be
62 a generic time specification, like ‘1h’) seconds into the future.
63 -k, --use-keytab
65 The same as --keytab, but with the default keytab name (normally
66 FILE:/etc/krb5.keytab).
67 -v, --validate
69 Try to validate an invalid ticket.
70 -e, --enctypes=enctypes
72 Request tickets with this particular enctype.
73 --password-file=filename
75 read the password from the first line of filename. If the
76 filename is STDIN, the password will be read from the standard
77 input.
78 --fcache-version=version-number
80 Create a credentials cache of version version-number.
81 -a, --extra-addresses=enctypes
83 Adds a set of addresses that will, in addition to the systems lo‐
84 cal addresses, be put in the ticket. This can be useful if all
85 addresses a client can use can't be automatically figured out.
86 One such example is if the client is behind a firewall. Also
87 settable via libdefaults/extra_addresses in krb5.conf(5).
88 -A, --no-addresses
90 Request a ticket with no addresses.
91 -n, --anonymous
93 Request an anonymous ticket. With the default (false) setting of
94 the historical_anon_pkinit configuration parameter, if the prin‐
95 cipal is specified as @REALM, then anonymous PKINIT will be used
96 to acquire an unauthenticated anonymous ticket and both the
97 client name and (with fully RFC-comformant KDCs) realm in the re‐
98 turned ticket will be anonymized. Otherwise, authentication pro‐
99 ceeds as normal and the anonymous ticket will have only the
100 client name anonymized. With historical_anon_pkinit set to true,
101 the principal is interpreted as a realm even without an at-sign
102 prefix, and it is not possible to obtain authenticated anonymized
103 tickets.
104 --enterprise
106 Parse principal as a enterprise (KRB5-NT-ENTERPRISE) name. Enter‐
107 prise names are email like principals that are stored in the name
108 part of the principal, and since there are two @ characters the
109 parser needs to know that the first is not a realm. An example
110 of an enterprise name is “lha@e.kth.se@KTH.SE”, and this option
111 is usually used with canonicalize so that the principal returned
112 from the KDC will typically be the real principal name.
113 --afslog
115 Gets AFS tickets, converts them to version 4 format, and stores
116 them in the kernel. Only useful if you have AFS.
117 The forwardable, proxiable, ticket_life, and renewable_life options can
119 be set to a default value from the appdefaults section in krb5.conf, see
120 krb5_appdefault(3).
121 If a command is given, kinit will set up new credentials caches, and AFS
123 PAG, and then run the given command. When it finishes the credentials
124 will be removed.
125
127 KRB5CCNAME
128 Specifies the default credentials cache.
129 KRB5_CONFIG
131 The file name of krb5.conf, the default being /etc/krb5.conf.
132
134 kdestroy(1), klist(1), krb5_appdefault(3), krb5.conf(5)
