SYNOPSIS

DESCRIPTION
ldapmodrdn is a shell-accessible interface to the ldap_rename(3) library
call.
ldapmodrdn opens a connection to an LDAP server, binds, and modifies the
RDN of entries. The entry information is read from standard input, from
file through the use of the -f option, or from the command-line pair dn
and rdn.
OPTIONS
-V[V] Print version info. If -VV is given, only the version informa-
tion is printed.
-d debuglevel
Set the LDAP debugging level to debuglevel. ldapmodrdn must be
compiled with LDAP_DEBUG defined for this option to have any ef-
fect.
-n Show what would be done, but don't actually change entries. Use-
ful for debugging in conjunction with -v.
-v Use verbose mode, with many diagnostics written to standard out-
put.
-r Remove old RDN values from the entry. Default is to keep old
values.
-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 sup-
ported in LDAPv2.
-c Continuous operation mode. Errors are reported, but ldapmod-
rdn will continue with modifications. The default is to exit
after reporting an error.
-f file
Read the entry modification information from file instead of from
standard input or the command-line.
-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 speci-
fying 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); only the proto-
col/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 modrdn 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)
Modrdn extensions:
(none)
-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
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 suc-
cessful.
INPUT FORMAT
If the command-line arguments dn and rdn are given, rdn will replace the
RDN of the entry specified by the DN, dn.
Otherwise, the contents of file (or standard input if no -f flag is
given) should consist of one or more entries.
Distinguished Name (DN)
Relative Distinguished Name (RDN)
One or more blank lines may be used to separate each DN/RDN pair.
EXAMPLE
Assuming that the file /tmp/entrymods exists and has the contents:
cn=Modify Me,dc=example,dc=com
cn=The New Me
the command:
ldapmodrdn -r -f /tmp/entrymods
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.
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.
