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
84 local 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. If the principal is specified as
94 @REALM, then anonymous PKINIT will be used to acquire an unau‐
95 thenticated anonymous ticket and both the client name and realm
96 in the returned ticket will be anonymized. Otherwise, authenti‐
97 cation proceeds as normal and the anonymous ticket will have only
98 the client name anonymized.
99 --enterprise
101 Parse principal as a enterprise (KRB5-NT-ENTERPRISE) name. Enter‐
102 prise names are email like principals that are stored in the name
103 part of the principal, and since there are two @ characters the
104 parser needs to know that the first is not a realm. An example
105 of an enterprise name is “lha@e.kth.se@KTH.SE”, and this option
106 is usually used with canonicalize so that the principal returned
107 from the KDC will typically be the real principal name.
108 --afslog
110 Gets AFS tickets, converts them to version 4 format, and stores
111 them in the kernel. Only useful if you have AFS.
112 The forwardable, proxiable, ticket_life, and renewable_life options can
114 be set to a default value from the appdefaults section in krb5.conf, see
115 krb5_appdefault(3).
116 If a command is given, kinit will set up new credentials caches, and AFS
118 PAG, and then run the given command. When it finishes the credentials
119 will be removed.
120
122 KRB5CCNAME
123 Specifies the default credentials cache.
124 KRB5_CONFIG
126 The file name of krb5.conf, the default being /etc/krb5.conf.
127
129 kdestroy(1), klist(1), krb5_appdefault(3), krb5.conf(5)
