LDAPCOMPARE(1) General Commands Manual LDAPCOMPARE(1)
NAME
ldapcompare - LDAP compare tool
SYNOPSIS
ldapcompare [-n] [-v] [-z] [-M[M]] [-d debuglevel] [-D binddn] [-W] [-w passwd] [-y passwdfile] [-H ldapuri] [-h ldaphost] [-p ldapport]
[-P {2|3}] [-e [!]ext[=extparam]] [-E [!]ext[=extparam]] [-O security-properties] [-I] [-Q] [-U authcid] [-R realm] [-x] [-X authzid]
[-Y mech] [-Z[Z]] DN {attr:value | attr::b64value}
DESCRIPTION
ldapcompare is a shell-accessible interface to the ldap_compare_ext(3) library call.
ldapcompare opens a connection to an LDAP server, binds, and performs a compare using specified parameters. The DN should be a distin-
guished name in the directory. Attr should be a known attribute. If followed by one colon, the assertion value should be provided as a
string. If followed by two colons, the base64 encoding of the value is provided. The result code of the compare is provided as the exit
code and, unless ran with -z, the program prints TRUE, FALSE, or UNDEFINED on standard output.
OPTIONS
-n Show what would be done, but don't actually perform the compare. Useful for debugging in conjunction with -v.
-v Run in verbose mode, with many diagnostics written to standard output.
-z Run in quiet mode, no output is written. You must check the return status. Useful in shell scripts.
-M[M] Enable manage DSA IT control. -MM makes control critical.
-d debuglevel
Set the LDAP debugging level to debuglevel. ldapcompare must be compiled with LDAP_DEBUG defined for this option to have any
effect.
-x Use simple authentication instead of SASL.
-D binddn
Use the Distinguished Name binddn to bind to the LDAP directory. For SASL binds, the server is expected to ignore this value.
-W Prompt for simple authentication. This is used instead of specifying the password on the command line.
-w passwd
Use passwd as the password for simple authentication.
-y passwdfile
Use complete contents of passwdfile as the password for simple authentication. Note that complete means that any leading or trail-
ing whitespaces, including newlines, will be considered part of the password and, unlike other software, they will not be stripped.
As a consequence, passwords stored in files by commands like echo(1) will not behave as expected, since echo(1) by default appends a
trailing newline to the echoed string. The recommended portable way to store a cleartext password in a file for use with this
option is to use slappasswd(8) with {CLEARTEXT} as hash and the option -n.
-H ldapuri
Specify URI(s) referring to the ldap server(s); only the protocol/host/port fields are allowed; a list of URI, separated by white-
space or commas is expected.
-h ldaphost
Specify an alternate host on which the ldap server is running. Deprecated in favor of -H.
-p ldapport
Specify an alternate TCP port where the ldap server is listening. Deprecated in favor of -H.
-P {2|3}
Specify the LDAP protocol version to use.
-e [!]ext[=extparam]
-E [!]ext[=extparam]
Specify general extensions with -e and search extensions with -E. '!' indicates criticality.
General extensions:
[!]assert=<filter> (an RFC 4515 Filter)
[!]authzid=<authzid> ("dn:<dn>" or "u:<user>")
[!]manageDSAit
[!]noop
ppolicy
[!]postread[=<attrs>] (a comma-separated attribute list)
[!]preread[=<attrs>] (a comma-separated attribute list)
abandon, cancel (SIGINT sends abandon/cancel; not really controls)
Search extensions:
[!]domainScope (domain scope)
[!]mv=<filter> (matched values filter)
[!]pr=<size>[/prompt|noprompt] (paged results/prompt)
[!]sss=[-]<attr[:OID]>[/[-]<attr[:OID]>...] (server side sorting)
[!]subentries[=true|false] (subentries)
[!]sync=ro[/<cookie>] (LDAP Sync refreshOnly)
rp[/<cookie>][/<slimit>] (LDAP Sync refreshAndPersist)
-O security-properties
Specify SASL security properties.
-I Enable SASL Interactive mode. Always prompt. Default is to prompt only as needed.
-Q Enable SASL Quiet mode. Never prompt.
-U authcid
Specify the authentication ID for SASL bind. The form of the ID depends on the actual SASL mechanism used.
-R realm
Specify the realm of authentication ID for SASL bind. The form of the realm depends on the actual SASL mechanism used.
-X authzid
Specify the requested authorization ID for SASL bind. authzid must be one of the following formats: dn:<distinguished name> or
u:<username>
-Y mech
Specify the SASL mechanism to be used for authentication. If it's not specified, the program will choose the best mechanism the
server knows.
-Z[Z] Issue StartTLS (Transport Layer Security) extended operation. If you use -ZZ, the command will require the operation to be success-
ful.
EXAMPLES
ldapcompare "uid=babs,dc=example,dc=com" sn:Jensen
ldapcompare "uid=babs,dc=example,dc=com" sn::SmVuc2Vu
are all equivalent.
LIMITATIONS
Requiring the value be passed on the command line is limiting and introduces some security concerns. The command should support a mecha-
nism to specify the location (file name or URL) to read the value from.
