       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.
