Using ldapbind to Authenticate

Question

I'm trying to run ldapbind to authenticate to an LDAP server. From running Java code that attempts to connect via LDAP, I know that a "Connection Timeout Error" is occurring.

However, am I running this ldapbind correctly? Note that I have a blank "userDn" or password used to access this server.

ldapbind -h ldap://A.B.C.com:389/dc=foo,dc=bar -D "" -w ""

Error: "Cannot connect to the LDAP server"

Solution

the following worked for me:

ldapbind -p 389 -h A.B.C.com -D "" -w ""

For my hostname, A.B.C.com, I did not need the ldap:// protocol specified. Note that, for this hostname, I did not need a username or password, hence the "" entries.

Note that, after my LDAP server came back online, running the above command produced: bind successful.
