# ldapexop(1)

issue LDAP extended operations

## NAME

ldapexop - issue LDAP extended operations

## SYNOPSIS

ldapexop \[**-d** *level\]* \[**-D** *binddn\]* \[**-e** \[**!**\]***ext***\[**=*extparam***\]\] \[**-f** *file\]* \[**-h** *host\]* \[**-H** *URI\]* \[**-I**\] \[**-n**\] \[**-N**\] \[**-O** *security-properties\]* \[**-o** *opt\[***=***optparam\]\]* \[**-p** *port\]* \[**-Q**\] \[**-R** *realm\]* \[**-U** *authcid\]* \[**-v**\] \[**-V**\] \[**-w** *passwd\]* \[**-W**\] \[**-x**\] \[**-X** *authzid\]* \[**-y** *file\]* \[**-Y** *mech\]* \[**-Z**\[**Z**\]\] {*oid* \| **oid:***data* \| **oid::***b64data* \| **whoami** \| **cancel** *cancel-id* \| **refresh** *DN* **\[*ttl*\]}**

## DESCRIPTION

ldapexop issues the LDAP extended operation specified by **oid** or one of the special keywords **whoami**, **cancel**, or **refresh**.

Additional data for the extended operation can be passed to the server using *data* or base-64 encoded as *b64data* in the case of **oid**, or using the additional parameters in the case of the specially named extended operations above.

Please note that ldapexop behaves differently for the same extended operation when it was given as an OID or as a specialliy named operation:

Calling ldapexop with the OID of the **whoami** (RFC 4532) extended operation

```
  ldapexop [<options>] 1.3.6.1.4.1.4203.1.11.3
```

yields

```
  # extended operation response
  data:: <base64 encoded response data>
```

while calling it with the keyword **whoami**

```
  ldapexop [<options>] whoami
```

results in

```
  dn:<client's identity>
```

## OPTIONS

- **-d** *level*

  Set the LDAP debugging level to *level*.

- **-D** *binddn*

  Use the Distinguished Name *binddn* to bind to the LDAP directory.

- **-e** \[**!**\]***ext***\[**=*extparam***\]

  Specify general extensions.  ´!´ indicates criticality.

  ```
    [!]assert=<filter>     (RFC 4528; a RFC 4515 Filter string)
    [!]authzid=<authzid>   (RFC 4370; "dn:<dn>" or "u:<user>")
    [!]chaining[=<resolveBehavior>[/<continuationBehavior>]]
       one of "chainingPreferred", "chainingRequired",
       "referralsPreferred", "referralsRequired"
    [!]manageDSAit         (RFC 3296)
    [!]noop
    ppolicy
    [!]postread[=<attrs>]  (RFC 4527; comma-separated attr list)
    [!]preread[=<attrs>]   (RFC 4527; comma-separated attr list)
    [!]relax
    abandon, cancel, ignore (SIGINT sends abandon/cancel,
    or ignores response; if critical, doesn't wait for SIGINT.
    not really controls)
  ```

- **-f** *file*

  Read operations from *file*.

- **-h** *host*

  Specify the host on which the ldap server is running. Deprecated in favor of **-H**.

- **-H** *URI*

  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.

- **-I**

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

- **-n**

  Show what would be done but don't actually do it. Useful for debugging in conjunction with **-v**.

- **-N**

  Do not use reverse DNS to canonicalize SASL host name.

- **-O** *security-properties*

  Specify SASL security properties.

- **-o** *opt\[***=***optparam\]*

  Specify general options:

  ```
    nettimeout=<timeout> (in seconds, or "none" or "max")
  ```

- **-p** *port*

  Specify the TCP port where the ldap server is listening. Deprecated in favor of **-H**.

- **-Q**

  Enable SASL Quiet mode.  Never prompt.

- **-R** *realm*

  Specify the realm of authentication ID for SASL bind. The form of the realm depends on the actual SASL mechanism used.

- **-U** *authcid*

  Specify the authentication ID for SASL bind. The form of the ID depends on the actual SASL mechanism used.

- **-v**

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

- **-V**

  Print version info and usage message. If**-VV** is given, only the version information is printed.

- **-w** *passwd*

  Use *passwd* as the password for simple authentication.

- **-W**

  Prompt for simple authentication. This is used instead of specifying the password on the command line.

- **-x**

  Use simple authentication instead of SASL.

- **-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** *file*

  Use complete contents of *file* as the password for simple authentication.

- **-Y** *mech*

  Specify the SASL mechanism to be used for authentication. Without this option, the program will choose the best mechanism the server knows.

- **-Z**\[**Z**\]

  Issue StartTLS (Transport Layer Security) extended operation. Giving it twice (**-ZZ**) will require the operation to be successful.

## 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.
