ldap_search_ext_s for user failed

[nathan_nz]

Hi everybody..

after so much of googling I am putting it here.

The problem is ..

I have used .htaccess for ldap authentication.
It was working properly. but after I recompile bith Openldap and apache and php, it started giving this error.

[ldap_search_ext_s for user failed][cant contact ldap server]

The settings in all the three is OK.

Can u please tell me what is the reason for this.

Thanks in advance
