For my login system, I must check a password against an online LDAP server using PHP.

Can anybody let me know if just checking a person against LDAP works with an affordable hosting plan from the company for example GoDaddy, 1&1, or Dreamhost?

Ex:

$objConn = ldap_connect($strDomain)

I'd rather not run an LDAP server, simply make use of the LDAP functions of PHP to ensure a merchant account.

Your best option is always to email their particular support departments and request this exact question I am sure they'll have the ability to assist you to. Everyone's setup will probably be different, making this most likely a great way. As lengthy because the support is put together-in plus you've got network connectivity for your LDAP host (that you simply should most likely access over SSL/TLS, if at all possible), you ought to be fine.
