How to authenticate ldap server to query?

I am using ldapsearch command and getting below error while querying:

$ ldapsearch -x "(objectclass=*)"
# extended LDIF
# LDAPv3
# base <dc=goexample,dc=me> (default) with scope subtree
# filter: (objectclass=*)
# requesting: ALL

# search result
search: 2
result: 1 Operations error
text: 00002020: Operation unavailable without authentication

# numResponses: 1

Open in new window

content of /etc/openldap/ldap.conf
# LDAP Defaults

# See ldap.conf(5) for details
# This file should be world readable but not world writable.

#BASE   dc=example,dc=com
#URI    ldap:// ldap://

#SIZELIMIT      12
#TIMELIMIT      15
#DEREF          never

BASE    dc=goexample,dc=me
URI     ldap://
TLS_CACERTDIR /etc/openldap/cacerts

Open in new window

I think I am getting authentication error.. I can I supply a userid and password with ldapsearch command?

You can use the -D and the -w/-W options.

1. "-D" indicates the username being used for the search
2. "-W" will make ldapsearch prompt you for the password associated with the "-D" option
3. "-w" is the password for the "-D" option.  Meaning you type your password in the command line command.
