LDAPCOMPARE(1)

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 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.

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 registered 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 authentication.

-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. Deprecated 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 proxy 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.

EXAMPLE
    ldapcompare "uid=babs,dc=example,dc=com"  sn Jensen
    ldapcompare "uid=babs,dc=example,dc=com"  sn:Jensen
    ldapcompare "uid=babs,dc=example,dc=com"  sn::SmVuc2Vu
are all equivalent.

DIAGNOSTICS
When -z is used, exit status is either 5 if the compare is false, or 6 when the compare is true. Errors result in other non-zero values.
When -z is not used, exit status is zero if no errors occur. Errors result in a non-zero exit status and a diagnostic message being written to standard error.

BUGS
Should have a way to specify a url for options or for large binary file compares.
