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.
