ldapwhoami1

Usage

Overview

ldapwhoami implements the LDAP "Who Am I?" extended operation.

ldapwhoami opens a connection to an LDAP server, binds, and performs a whoami operation.

Options

-n

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

-v

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

-d debuglevel

Set the LDAP debugging level to debuglevel. ldapwhoami must be compiled with LDAP_DEBUG defined for this option to have any effect.

-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.

-O security-properties

Specify SASL security properties.

-e [!]ext[=extparam]

-E [!]ext[=extparam]

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>")
  [!]manageDSAit
  [!]noop
  ppolicy
  [!]postread[=<attrs>]        (a comma-separated attribute list)
  [!]preread[=<attrs>] (a comma-separated attribute list)
  abandon, cancel (SIGINT sends abandon/cancel; 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)

-I

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

-Q

Enable SASL Quiet mode. Never prompt.

-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.

Examples

    ldapwhoami -x -D "cn=Manager,dc=example,dc=com" -W
