LDAPCOMPARE(1) FreeBSD General Commands Manual LDAPCOMPARE(1)
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] [-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 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.
-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[=<username>] 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 any ldap.conf(5) option or one of the following: 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
-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.
