LDAP verify credentials tool

Synopsis

ldapvc [-V[V]] [-d debuglevel] [-a] [-b] [-n] [-v] [-x] [-D binddn] [-W] [-w passwd] [-y passwdfile] [-H ldapuri] [-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]] Distinguished Name [Credentials]

Description

ldapvc implements the LDAP "Verify Credentials" extended operation.

Verify Credentials operation behaves like LDAP Bind but has no impact upon the underlying LDAP session.

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

-a

Print the authzID resulting from a successful verification of credentials.

-b

Print the results from the ppolicy control after verification of credentials.

-n

Show what would be done, but don't actually perform the 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.

-e [!]ext[=extparam]
-E [!]ext[=extparam]

Specify general extensions with -e and Verify Credentials extensions with -E. ´!´ indicates criticality.

General extensions:

  [!]assert=<filter>    (an RFC 4515 Filter)
  [!]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)

Verify Credentials extensions:

The following options set SASL params on the Verify Credentials request:

  authcid=<authcid>    (SASL Authentication Identity "dn:<dn>" or "u:<user>")
  authzid=<authzid>    (SASL Authorization Identity "dn:<dn>" or "u:<user>")
  mech=<mech>          (SASL mechanism default e.g. Simple)
  realm=<realm>        (SASL Realm, defaults to none)
  sasl=a[utomatic]|i[nteractive]|q[uiet]  (SASL mode defaults to automatic if any other -E option provided, otherwise none)
  secprops=<secprops>  (SASL Security Properties)
-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 option that can be passed here, check ldap.conf(5) for details.

-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

    ldapvc -x "uid=Alice,ou=People,dc=example,dc=com"
