PHP Warning: ldap_bind(): Unable to bind to server: Can't contact LDAP server

Question

I\'ve following problem with my php script:

PHP Warning: ldap_bind(): Unable to bind to server: Can\'t contact LDAP server in ....

Answer 1

the ldap_bind() function asks for a three parameters:

1. a resource id
2. a rdn
3. a password associated with the rdn the rdn and password are optional

if you bind using only the resource id :-

// $ldap=ladap_connect(*hostname*,*port*);  
// ldap_connect() returns a resource id
ldap_bind() returns a boolean value(true or false)  
ldap_bind($ladp); //annonymous bind    
$lb=ldap_bind($ldap,"uid=xxx,ou=something,o=hostname.com","password"); //used to authenticate  

this should work if not then you are using invalid credentials.
