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]] Distin- guished 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 cre- dentials. -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 out- put. -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 specify- ing 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 au- thentication. -H ldapuri Specify URI(s) referring to the ldap server(s); only the proto- col/host/port fields are allowed; a list of URI, separated by white- space 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 re- quest: 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 de- pends 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:<user- name> -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.
