17 ldapcompare is a shell-accessible interface to the ldap_compare_ext(3)
18 library call.
19 ldapcompare opens a connection to an LDAP server, binds, and performs a
21 compare using specified parameters. The DN should be a distinguished
22 name in the directory. Attr should be a known attribute. If followed
23 by one colon, the assertion value should be provided as a string. If
24 followed by two colons, the base64 encoding of the value is provided.
25 The result code of the compare is provided as the exit code and, unless
26 ran with -z, the program prints TRUE, FALSE, or UNDEFINED on standard
27 output.
28
30 -V[V] Print version info. If -VV is given, only the version informa‐
31 tion is printed.
32 -d debuglevel
34 Set the LDAP debugging level to debuglevel. ldapcompare must be
35 compiled with LDAP_DEBUG defined for this option to have any ef‐
36 fect.
37 -n Show what would be done, but don't actually perform the compare.
39 Useful for debugging in conjunction with -v.
40 -v Run in verbose mode, with many diagnostics written to standard
42 output.
43 -z Run in quiet mode, no output is written. You must check the re‐
45 turn status. Useful in shell scripts.
46 -M[M] Enable manage DSA IT control. -MM makes control critical.
48 -x Use simple authentication instead of SASL.
50 -D binddn
52 Use the Distinguished Name binddn to bind to the LDAP directory.
53 For SASL binds, the server is expected to ignore this value.
54 -W Prompt for simple authentication. This is used instead of spec‐
56 ifying the password on the command line.
57 -w passwd
59 Use passwd as the password for simple authentication.
60 -y passwdfile
62 Use complete contents of passwdfile as the password for simple
63 authentication. Note that complete means that any leading or
64 trailing whitespaces, including newlines, will be considered
65 part of the password and, unlike other software, they will not
66 be stripped. As a consequence, passwords stored in files by
67 commands like echo(1) will not behave as expected, since echo(1)
68 by default appends a trailing newline to the echoed string. The
69 recommended portable way to store a cleartext password in a file
70 for use with this option is to use slappasswd(8) with {CLEART‐
71 EXT} as hash and the option -n.
72 -H ldapuri
74 Specify URI(s) referring to the ldap server(s); only the proto‐
75 col/host/port fields are allowed; a list of URI, separated by
76 whitespace or commas is expected.
77 -h ldaphost
79 Specify an alternate host on which the ldap server is running.
80 Deprecated in favor of -H.
81 -p ldapport
83 Specify an alternate TCP port where the ldap server is listen‐
84 ing. Deprecated in favor of -H.
85 -P {2|3}
87 Specify the LDAP protocol version to use.
88 -e [!]ext[=extparam]
90 -E [!]ext[=extparam]
92 Specify general extensions with -e and compare extensions with
94 -E. ´!´ indicates criticality.
95 General extensions:
97 [!]assert=<filter> (an RFC 4515 Filter)
98 !authzid=<authzid> ("dn:<dn>" or "u:<user>")
99 [!]bauthzid (RFC 3829 authzid control)
100 [!]chaining[=<resolve>[/<cont>]]
101 [!]manageDSAit
102 [!]noop
103 ppolicy
104 [!]postread[=<attrs>] (a comma-separated attribute list)
105 [!]preread[=<attrs>] (a comma-separated attribute list)
106 [!]relax
107 sessiontracking
108 abandon,cancel,ignore (SIGINT sends abandon/cancel,
109 or ignores response; if critical, doesn't wait for SIGINT.
110 not really controls)
111 Compare extensions:
113 !dontUseCopy
114 -o opt[=optparam]
116 Specify any ldap.conf(5) option or one of the following:
118 nettimeout=<timeout> (in seconds, or "none" or "max")
119 ldif_wrap=<width> (in columns, or "no" for no wrapping)
120 -O security-properties
123 Specify SASL security properties.
124 -I Enable SASL Interactive mode. Always prompt. Default is to
126 prompt only as needed.
127 -Q Enable SASL Quiet mode. Never prompt.
129 -N Do not use reverse DNS to canonicalize SASL host name.
131 -U authcid
133 Specify the authentication ID for SASL bind. The form of the ID
134 depends on the actual SASL mechanism used.
135 -R realm
137 Specify the realm of authentication ID for SASL bind. The form
138 of the realm depends on the actual SASL mechanism used.
139 -X authzid
141 Specify the requested authorization ID for SASL bind. authzid
142 must be one of the following formats: dn:<distinguished name> or
143 u:<username>
144 -Y mech
146 Specify the SASL mechanism to be used for authentication. If
147 it's not specified, the program will choose the best mechanism
148 the server knows.
149 -Z[Z] Issue StartTLS (Transport Layer Security) extended operation. If
151 you use -ZZ, the command will require the operation to be suc‐
152 cessful.
153
155 ldapcompare "uid=babs,dc=example,dc=com" sn:Jensen
156 ldapcompare "uid=babs,dc=example,dc=com" sn::SmVuc2Vu
157 are all equivalent.
158
160 Requiring the value be passed on the command line is limiting and in‐
161 troduces some security concerns. The command should support a mecha‐
162 nism to specify the location (file name or URL) to read the value from.
