NAMEldapcompare - LDAP compare tool
SYNOPSISldapcompare [-n] [-v] [-z] [-M[M]] [-d debuglevel] [-D binddn] [-W] [-w passwd] [-y passwdfile] [-H ldapuri] [-h ldaphost] [-p ldapport] [-P 2|3] [-O security-properties] [-I] [-Q] [-U authcid] [-R realm] [-x] [-X authzid] [-Y mech] [-Z[Z]] DN < attr:value | attr::b64value >
DESCRIPTIONldapcompare is a shell-accessible interface to the ldap_compare(3) library call.
ldapcompare opens a connection to an LDAP server, binds, and performs a compare using specified parameters. The DN should be a distinguished name in the directory. Attr should be a known attribute. If followed by one colon, the assertion value should be provided as a string. If followed by two colons, the base64 encoding of the value is provided. The result code of the compare is provided as the exit code and, unless ran with -z, the program prints TRUE, FALSE, or UNDEFINED on standard output.
- Show what would be done, but don't actually perform the compare. Useful for debugging in conjunction with -v.
- Run in verbose mode, with many diagnostics written to standard output.
- Run in quiet mode, no output is written. You must check the return status. Useful in shell scripts.
- Enable manage DSA IT control. -MM makes control critical.
- -d debuglevel
- Set the LDAP debugging level to debuglevel. ldapcompare must be compiled with LDAP_DEBUG defined for this option to have any effect.
- Use simple authentication instead of SASL.
- -D binddn
- Use the Distinguished Name binddn to bind to the LDAP directory.
- 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.
- -P 2|3
- Specify the LDAP protocol version to use.
- -O security-properties
- Specify SASL security properties.
- Enable SASL Interactive mode. Always prompt. Default is to prompt only as needed.
- Enable SASL Quiet mode. Never prompt.
- -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.
- Issue StartTLS (Transport Layer Security) extended operation. If you use -ZZ, the command will require the operation to be successful.
ldapcompare "uid=babs,dc=example,dc=com" sn:Jensen ldapcompare "uid=babs,dc=example,dc=com" sn::SmVuc2Vuare all equivalent.
LIMITATIONSRequiring the value be passed on the command line is limiting and introduces some security concerns. The command should support a mechanism to specify the location (file name or URL) to read the value from.
