ldapmodrdn is a shell-accessible interface to the ldap_rename(3)
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.
-V[V] Print version info. If -VV is given, only the version
information is printed.
Set the LDAP debugging level to debuglevel. ldapmodrdn must
be compiled with LDAP_DEBUG defined for this option to have
-n Show what would be done, but don't actually change entries.
Useful for debugging in conjunction with -v.
-v Use verbose mode, with many diagnostics written to standard
-r Remove old RDN values from the entry. Default is to keep old
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.
-c Continuous operation mode. Errors are reported, but
ldapmodrdn will continue with modifications. The default
is to exit after reporting an error.
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.
Use the Distinguished Name binddn to bind to the LDAP
directory. For SASL binds, the server is expected to ignore
-W Prompt for simple authentication. This is used instead of
specifying the password on the command line.
Use passwd as the password for simple authentication.
Use complete contents of passwdfile as the password for simple
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.
Specify an alternate host on which the ldap server is running.
Deprecated in favor of -H.
Specify an alternate TCP port where the ldap server is
listening. Deprecated in favor of -H.
Specify the LDAP protocol version to use.
Specify general extensions with -e and modrdn extensions with
-E. ´!´ indicates criticality.
[!]assert=<filter> (an RFC 4515 Filter)
!authzid=<authzid> ("dn:<dn>" or "u:<user>")
[!]bauthzid (RFC 3829 authzid control)
[!]postread[=<attrs>] (a comma-separated attribute list)
[!]preread[=<attrs>] (a comma-separated attribute list)
abandon,cancel,ignore (SIGINT sends abandon/cancel,
or ignores response; if critical, doesn't wait for SIGINT.
not really controls)
Specify general options.
nettimeout=<timeout> (in seconds, or "none" or "max")
ldif-wrap=<width> (in columns, or "no" for no wrapping)
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.
Specify the authentication ID for SASL bind. The form of the
ID depends on the actual SASL mechanism used.
Specify the realm of authentication ID for SASL bind. The form
of the realm depends on the actual SASL mechanism used.
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
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.
Assuming that the file /tmp/entrymods exists and has the contents:
cn=The New Me
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.
