ldapmodrdn is a shell-accessible interface to the ldap_rename() 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.



Print version info. If -VV is given, only the version information is printed.

-d debuglevel 

Set the LDAP debugging level to debuglevel. ldapsearch must be compiled with LDAP_DEBUG defined for this option to have any effect. The PTC MKS Toolkit port does not define LDAP_DEBUG.


Show what would be done, but don't actually perform the search. Useful for debugging in conjunction with -v.


Run in verbose mode, with many diagnostics written to standard output.


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 supported in LDAPv2.


Continuous operation mode. Errors are reported, but ldapsearch will continue with searches. The default is to exit after reporting an error. Only useful in conjunction with -f.

-f file 

Read the entry modification information from file instead of from standard input.


Enable manage DSA IT control. -MM makes control critical.


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.


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.

-H ldapuri 

Specify URI(s) referring to the ldap server(s); a list of URI, separated by whitespace or commas is expected; only the protocol/host/port fields are allowed. As an exception, if no host/port is specified, but a DN is, the DN is used to look up the corresponding host(s) using the DNS SRV records, according to RFC 2782. The DN must be a non-empty sequence of AVAs whose attribute type is "dc" (domain component), and must be escaped according to RFC 2396.

-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.


Specify the LDAP protocol version to use.


Specify general extensions with -e and search extensions with -E. '!' indicates criticality. General extensions:

[!]assert=<filter>   (an RFC 4515 Filter)
[!]authzid=<authzid> ("dn:<dn>" or "u:<user>")
[!]postread[=<attrs>]        (a comma-separated attribute list)
[!]preread[=<attrs>] (a comma-separated attribute list)
abandon,cancel,ignore (SIGINT sends abandon/cancel; or ignores repsonse; ; If critical doesn't wait for SIGINT. not really controls)

Search extensions:

[!]domainScope                       (domain scope)
[!]mv=<filter>                       (matched values filter)
[!]pr=<size>[/prompt|noprompt]       (paged results/prompt)
[!]sss=[-]<attr[:OID]>[/[-]<attr[:OID]>...]  (server side sorting)
[!]subentries[=true|false]           (subentries)
[!]sync=ro[/<cookie>]                (LDAP Sync refreshOnly)
        rp[/<cookie>][/<slimit>]     (LDAP Sync refreshAndPersist)
[!]vlv=<before>/<after>(/<offset>/<count>|:<value>)  (virtual list view)
-o opt[=optparam

Specify general options. General options:

nettimeout=<timeout>  (in seconds, or "none" or "max")
-O security-properties 

Specify SASL security properties.


Enable SASL Interactive mode. Always prompt. Default is to prompt only as needed.


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.


Issue StartTLS (Transport Layer Security) extended operation. If you use -ZZ, the command will require the operation to be successful.


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=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.


Possible exit status values are: Exit status is zero if no errors occur. Errors result in a non-zero exit status and a diagnostic message being written to standard error.
