ldapwhoami – LDAP who am i? tool

Synopsis

ldapwhoami [-V[V]] [-d debuglevel] [-n] [-v] [-x] [-D binddn] [-W] [-w passwd] [-y passwdfile] [-H ldapuri] [-h ldaphost] [-p ldapport] [-e [!]ext[=extparam]] [-E [!]ext[=extparam]] [-o opt[=optparam]] [-O security-properties] [-I] [-Q] [-N] [-U authcid] [-R realm] [-X authzid] [-Y mech] [-Z[Z]]

Description

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

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

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

-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.

-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.

-e [!]ext[=extparam]

-E [!]ext[=extparam]

Specify general extensions with -e and whoami 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)

WhoAmI extensions:

 (none)

-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.

Example

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