Problem Login via LDAP

Hello i made a mistake, i saved in my admin account The log via LDAP. Now when i try to enter to OJS it appears The following error “Fatal Error: call to undefined function ldap_connect() in/web/htdocs/www…it/home/plugins/auth/ldap/LDAPAuthPkugin.inc.php on line 239”.

I dont know how can disable login via LDAP without entering OJS or in any case how can i rsesolve this situation…
Thanks
