ldapmodrdn1

Usage

Overview

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 information 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 effect.

-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 output.

-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 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.

-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 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); only the protocol/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 successful.

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.

Examples

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.
