NAME
ldapcompare - LDAP compare tool
SYNOPSIS
ldapcompare [-n] [-v] [-z] [-k] [-K] [-M[M]] [-d debuglevel] [-D binddn] [-W]
[-w passwd] [-y passwdfile] [-H ldapuri] [-h ldaphost] [-p ldapport] [-P 2|3]
[-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(3) library call.
ldapcompare opens a connection to an LDAP server, binds, and performs a compare
using specified parameters. The DN should be a distinguished name in the direc-
tory. 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 encod-
ing 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.
-k Use Kerberos IV authentication instead of simple authentication. It is
assumed that you already have a valid ticket granting ticket. ldapcompare
must be compiled with Kerberos support for this option to have any effect.
-K Same as -k, but only does step 1 of the Kerberos IV bind. This is useful
when connecting to a slapd and there is no x500dsa.hostname principal regis-
tered with your Kerberos Domain Controller(s).
-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.
-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 authentica-
tion.
-H ldapuri
Specify URI(s) referring to the ldap server(s).
-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. Depre-
cated in favor of -H.
-P 2|3 Specify the LDAP protocol version to use.
-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 speci-
fied, 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 successful.
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 mechanism to specify the location
(file name or URL) to read the value from.
