LDAPVC(1) General Commands Manual LDAPVC(1)
NAME
ldapvc - 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"
