NAME
ldapcompare - LDAP compare tool
SYNOPSIS
ldapcompare [-V[V]] [-d debuglevel] [-n] [-v] [-z] [-M[M]] [-x]
[-D binddn] [-W] [-w passwd] [-y passwdfile] [-H ldapuri] [-h ldaphost]
[-p ldapport] [-P {2|3}] [-e [!]ext[=extparam]] [-E [!]ext[=extparam]]
[-o opt[=optparam]] [-O security-properties] [-I] [-Q] [-N]
[-U authcid] [-R realm] [-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 distinguished 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
-V[V] Print version info. If -VV is given, only the version
information is printed.
-d debuglevel
Set the LDAP debugging level to debuglevel. ldapcompare must be
compiled with LDAP_DEBUG defined for this option to have any
effect.
-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.
-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
trailing 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 whitespace 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 compare extensions with
-E. ! indicates criticality.
General extensions:
[!]assert=<filter> (an RFC 4515 Filter)
!authzid=<authzid> ("dn:<dn>" or "u:<user>")
[!]bauthzid (RFC 3829 authzid control)
[!]chaining[=<resolve>[/<cont>]]
[!]manageDSAit
[!]noop
ppolicy
[!]postread[=<attrs>] (a comma-separated attribute list)
[!]preread[=<attrs>] (a comma-separated attribute list)
[!]relax
sessiontracking
abandon,cancel,ignore (SIGINT sends abandon/cancel,
or ignores response; if critical, doesn't wait for SIGINT.
not really controls)
Compare extensions:
!dontUseCopy
-o opt[=optparam]
Specify general options.
General options:
nettimeout=<timeout> (in seconds, or "none" or "max")
ldif-wrap=<width> (in columns, or "no" for no wrapping)
-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.
-N Do not use reverse DNS to canonicalize SASL host name.
-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
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.
