.SH DESCRIPTION
.I ldapcompare
is a shell-accessible interface to the
.BR ldap_compare_ext (3)
library call.
.LP
.B ldapcompare
opens a connection to an LDAP server, binds, and performs a compare
using specified parameters.   The \fIDN\fP should be a distinguished
name in the directory.  \fIAttr\fP should be a known attribute.  If
followed by one colon, the assertion \fIvalue\fP 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.
.LP
.SH OPTIONS
.TP
.B \-n
Show what would be done, but don't actually perform the compare.  Useful for
debugging in conjunction with -v.
.TP
.B \-v
Run in verbose mode, with many diagnostics written to standard output.
.TP
.B \-z
Run in quiet mode, no output is written.  You must check the return
status.  Useful in shell scripts.
.TP
.B \-M[M]
Enable manage DSA IT control.
.B \-MM
makes control critical.
.TP
.BI \-d \ debuglevel
Set the LDAP debugging level to \fIdebuglevel\fP.
.B ldapcompare
must be compiled with LDAP_DEBUG defined for this option to have any effect.
.TP
.B \-x 
Use simple authentication instead of SASL.
.TP
.BI \-D \ binddn
Use the Distinguished Name \fIbinddn\fP to bind to the LDAP directory.
.TP
.B \-W
Prompt for simple authentication.
This is used instead of specifying the password on the command line.
.TP
.BI \-w \ passwd
Use \fIpasswd\fP as the password for simple authentication.
.TP
.BI \-y \ passwdfile
Use complete contents of \fIpasswdfile\fP as the password for
simple authentication.
.TP
.BI \-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.
.TP
.BI \-h \ ldaphost
Specify an alternate host on which the ldap server is running.
Deprecated in favor of -H.
.TP
.BI \-p \ ldapport
Specify an alternate TCP port where the ldap server is listening.
Deprecated in favor of -H.
.TP
.BI \-P \ 2\fR\||\|\fI3
Specify the LDAP protocol version to use.
.TP
.BI \-O \ security-properties
Specify SASL security properties.
.TP
.B \-I
Enable SASL Interactive mode.  Always prompt.  Default is to prompt
only as needed.
.TP
.B \-Q
Enable SASL Quiet mode.  Never prompt.
.TP
.BI \-U \ authcid
Specify the authentication ID for SASL bind. The form of the ID
depends on the actual SASL mechanism used.
.TP
.BI \-R \ realm
Specify the realm of authentication ID for SASL bind. The form of the realm
depends on the actual SASL mechanism used.
.TP
.BI \-X \ authzid
Specify the requested authorization ID for SASL bind.
.I authzid
must be one of the following formats:
.B dn:\c
.I <distinguished name>
or
.B u:\c
.I <username>
.TP
.BI \-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.
.TP
.B \-Z[Z]
Issue StartTLS (Transport Layer Security) extended operation. If you use
.B \-ZZ\c
, the command will require the operation to be successful.
.SH EXAMPLES
.nf
    ldapcompare "uid=babs,dc=example,dc=com"  sn:Jensen
    ldapcompare "uid=babs,dc=example,dc=com"  sn::SmVuc2Vu
.fi
are all equivalent.
.SH 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.
