Description

ldapmodify is a shell-accessible interface to the ldap_add_ext(3), ldap_modify_ext(3), ldap_delete_ext(3) and ldap_rename(3). library calls. ldapadd is implemented as a hard link to the ldapmodify tool.  When invoked as ldapadd the -a (add new entry) flag is turned on automatically.

ldapmodify opens a connection to an LDAP server, binds, and modifies or adds entries. The entry information is read from standard input or from file through the use of the -f option.

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. ldapmodify must be compiled with LDAP_DEBUG defined for this option to have any effect.

-n

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

-v

Use verbose mode, with many diagnostics written to standard output.

-a

Add new entries.  The default for ldapmodify is to modify existing entries.  If invoked as ldapadd, this flag is always set.

-c

Continuous operation mode.  Errors are reported, but ldapmodify 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.

-S file

Add or change records which were skipped due to an error are written to file  and the error message returned by the server is added as a comment. Most useful in  conjunction with -c.

-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.

-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.

-P {2|3}

Specify the LDAP protocol version to use.

-e [!]ext[=extparam]

-E [!]ext[=extparam]

Specify general extensions with -e and modify 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
  abandon,cancel,ignore (SIGINT sends abandon/cancel,
  or ignores response; if critical, doesn't wait for SIGINT.
  not really controls)

Modify extensions:

  [!]txn[=abort|commit]

-o opt[=optparam]]

Specify general options.

General options:

  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

The contents of file (or standard input if no -f flag is given on the command line) must conform to the format defined in ldif(5) (LDIF as defined in RFC 2849).

Examples

Assuming that the file /tmp/entrymods exists and has the contents:

    dn: cn=Modify Me,dc=example,dc=com
    changetype: modify
    replace: mail
    mail: modme@example.com
    -
    add: title
    title: Grand Poobah
    -
    add: jpegPhoto
    jpegPhoto:< file:///tmp/modme.jpeg
    -
    delete: description
    -

the command:

    ldapmodify -f /tmp/entrymods

will replace the contents of the "Modify Me" entry's mail attribute with the value "modme@example.com", add a title of "Grand Poobah", and the contents of the file "/tmp/modme.jpeg" as a jpegPhoto, and completely remove the description attribute.

Assuming that the file /tmp/newentry exists and has the contents:

    dn: cn=Barbara Jensen,dc=example,dc=com
    objectClass: person
    cn: Barbara Jensen
    cn: Babs Jensen
    sn: Jensen
    title: the world's most famous mythical manager
    mail: bjensen@example.com
    uid: bjensen

the command:

    ldapadd -f /tmp/newentry

will add a new entry for Babs Jensen, using the values from the file /tmp/newentry.

Assuming that the file /tmp/entrymods exists and has the contents:

    dn: cn=Barbara Jensen,dc=example,dc=com
    changetype: delete

the command:

    ldapmodify -f /tmp/entrymods

will remove Babs Jensen's entry.

Diagnostics

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.
