.SH DESCRIPTION
.B ldapmodrdn
is a shell-accessible interface to the
.BR ldap_rename (3)
library call.
.LP
.B ldapmodrdn
opens a connection to an LDAP server, binds, and modifies the RDN of entries.
The entry information is read from standard input, from \fIfile\fP through
the use of the
.RI \- f
option, or from the command-line pair \fIdn\fP and
\fIrdn\fP.
.SH OPTIONS
.TP
.BR \-V [ V ]
Print version info.
If \fB\-VV\fP is given, only the version information is printed.
.TP
.BI \-d \ debuglevel
Set the LDAP debugging level to \fIdebuglevel\fP.
.B ldapmodrdn
must be compiled with LDAP_DEBUG defined for this option to have any effect.
.TP
.B \-n
Show what would be done, but don't actually change entries.  Useful for
debugging in conjunction with \fB\-v\fP.
.TP
.B \-v
Use verbose mode, with many diagnostics written to standard output.
.TP
.B \-r
Remove old RDN values from the entry.  Default is to keep old values.
.TP
.BI \-s \ newsup
Specify a new superior entry. (I.e., move the target entry and make it a
child of the new superior.)  This option is not supported in LDAPv2.
.TP
.B \-c
Continuous operation mode.  Errors  are  reported,  but ldapmodrdn
will  continue  with  modifications.   The default is to exit after
reporting an error.
.TP
.BI \-f \ file
Read the entry modification information from \fIfile\fP instead of from
standard input or the command-line.
.TP
.BR \-M [ M ]
Enable manage DSA IT control.
.B \-MM
makes control critical.
.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.
For SASL binds, the server is expected to ignore this value.
.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
.BR \-P \ { 2 \||\| 3 }
Specify the LDAP protocol version to use.
.TP
.BR \-e \ [ ! ] \fIext\fP [ =\fIextparam\fP ]
.TP
.BR \-E \ [ ! ] \fIext\fP [ =\fIextparam\fP ]

Specify general extensions with \fB\-e\fP and modrdn extensions with \fB\-E\fP.
\'\fB!\fP\' indicates criticality.

General extensions:
.nf
  [!]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)
.fi

Modrdn extensions:
.nf
  (none)
.fi
.TP
.BI \-o \ opt \fR[= optparam \fR]

Specify any
.BR ldap.conf (5)
option or one of the following:
.nf
  nettimeout=<timeout>  (in seconds, or "none" or "max")
  ldif_wrap=<width>     (in columns, or "no" for no wrapping)
.fi

.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
.B \-N
Do not use reverse DNS to canonicalize SASL host name.
.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:
.BI dn: "<distinguished name>"
or
.BI u: <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
.BR \-Z [ Z ]
Issue StartTLS (Transport Layer Security) extended operation. If you use
\fB\-ZZ\fP, the command will require the operation to be successful.
.SH INPUT FORMAT
If the command-line arguments \fIdn\fP and \fIrdn\fP are given, \fIrdn\fP
will replace the RDN of the entry specified by the DN, \fIdn\fP.
.LP
Otherwise, the contents of \fIfile\fP (or standard input if
no \fB\-f\fP flag is given) should consist of one or more entries.
.LP
.nf
    Distinguished Name (DN)
    Relative Distinguished Name (RDN)
.fi
.LP
One or more blank lines may be used to separate each DN/RDN pair.
.SH EXAMPLE
Assuming that the file
.B /tmp/entrymods
exists and has the contents:
.LP
.nf
    cn=Modify Me,dc=example,dc=com
    cn=The New Me
.fi
.LP
the command:
.LP
.nf
    ldapmodrdn \-r \-f /tmp/entrymods
.fi
.LP
will change the RDN of the "Modify Me" entry from "Modify Me" to
"The New Me" and the old cn, "Modify Me" will be removed.
.LP
.SH DIAGNOSTICS
Exit status is 0 if no errors occur.  Errors result in a non-zero exit
status and a diagnostic message being written to standard error.
