9 ldapvc [-V[V]] [-d debuglevel] [-a] [-b] [-n] [-v] [-x] [-D binddn]
10 [-W] [-w passwd] [-y passwdfile] [-H ldapuri] [-e [!]ext[=extparam]]
11 [-E [!]ext[=extparam]] [-o opt[=optparam]] [-O security-properties]
12 [-I] [-Q] [-N] [-U authcid] [-R realm] [-X authzid] [-Y mech] [-Z[Z]]
13 Distinguished Name [Credentials]
14
16 ldapvc implements the LDAP "Verify Credentials" extended operation.
17
18 Verify Credentials operation behaves like LDAP Bind but has no impact
19 upon the underlying LDAP session.
20
22 -V[V] Print version info. If -VV is given, only the version informa‐
23 tion is printed.
24
25 -d debuglevel
26 Set the LDAP debugging level to debuglevel. ldapvc must be com‐
27 piled with LDAP_DEBUG defined for this option to have any ef‐
28 fect.
29
30 -a Print the authzID resulting from a successful verification of
31 credentials.
32
33 -b Print the results from the ppolicy control after verification of
34 credentials.
35
36 -n Show what would be done, but don't actually perform the opera‐
37 tion. Useful for debugging in conjunction with -v.
38
39 -v Run in verbose mode, with many diagnostics written to standard
40 output.
41
42 -x Use simple authentication instead of SASL.
43
44 -D binddn
45 Use the Distinguished Name binddn to bind to the LDAP directory.
46 For SASL binds, the server is expected to ignore this value.
47
48 -W Prompt for simple authentication. This is used instead of spec‐
49 ifying the password on the command line.
50
51 -w passwd
52 Use passwd as the password for simple authentication.
53
54 -y passwdfile
55 Use complete contents of passwdfile as the password for simple
56 authentication.
57
58 -H ldapuri
59 Specify URI(s) referring to the ldap server(s); only the proto‐
60 col/host/port fields are allowed; a list of URI, separated by
61 whitespace or commas is expected.
62
63 -e [!]ext[=extparam]
64
65 -E [!]ext[=extparam]
66
67 Specify general extensions with -e and Verify Credentials exten‐
68 sions with -E. ´!´ indicates criticality.
69
70 General extensions:
71 [!]assert=<filter> (an RFC 4515 Filter)
72 [!]bauthzid (RFC 3829 authzid control)
73 [!]chaining[=<resolve>[/<cont>]]
74 [!]manageDSAit
75 [!]noop
76 ppolicy
77 [!]postread[=<attrs>] (a comma-separated attribute list)
78 [!]preread[=<attrs>] (a comma-separated attribute list)
79 [!]relax
80 sessiontracking[=<username>]
81 abandon,cancel,ignore (SIGINT sends abandon/cancel,
82 or ignores response; if critical, doesn't wait for SIGINT.
83 not really controls)
84
85 Verify Credentials extensions:
86
87 The following options set SASL params on the Verify Credentials
88 request:
89 authcid=<authcid> (SASL Authentication Identity "dn:<dn>" or "u:<user>")
90 authzid=<authzid> (SASL Authorization Identity "dn:<dn>" or "u:<user>")
91 mech=<mech> (SASL mechanism default e.g. Simple)
92 realm=<realm> (SASL Realm, defaults to none)
93 sasl=a[utomatic]|i[nteractive]|q[uiet] (SASL mode defaults to automatic if any other -E option provided, otherwise none)
94 secprops=<secprops> (SASL Security Properties)
95
96 -o opt[=optparam]
97
98 Specify any ldap.conf(5) option or one of the following:
99 nettimeout=<timeout> (in seconds, or "none" or "max")
100 ldif_wrap=<width> (in columns, or "no" for no wrapping)
101
102 -o option that can be passed here, check ldap.conf(5) for de‐
103 tails.
104
105 -O security-properties
106 Specify SASL security properties.
107
108 -I Enable SASL Interactive mode. Always prompt. Default is to
109 prompt only as needed.
110
111 -Q Enable SASL Quiet mode. Never prompt.
112
113 -N Do not use reverse DNS to canonicalize SASL host name.
114
115 -U authcid
116 Specify the authentication ID for SASL bind. The form of the ID
117 depends on the actual SASL mechanism used.
118
119 -R realm
120 Specify the realm of authentication ID for SASL bind. The form
121 of the realm depends on the actual SASL mechanism used.
122
123 -X authzid
124 Specify the requested authorization ID for SASL bind. authzid
125 must be one of the following formats: dn:<distinguished name> or
126 u:<username>
127
128 -Y mech
129 Specify the SASL mechanism to be used for authentication. If
130 it's not specified, the program will choose the best mechanism
131 the server knows.
132
133 -Z[Z] Issue StartTLS (Transport Layer Security) extended operation. If
134 you use -ZZ, the command will require the operation to be suc‐
135 cessful.
136
138 ldapvc -x "uid=Alice,ou=People,dc=example,dc=com"
