Steps to reproduce the issue

Log in to the site / front-end with LDAP user or Joomla-registered user
Log in by admin / backend with LDAP user or Joomla registered user

Expected result

Access to the intranet / front-end website or access to the joomla administrative area or back-end

Actual result

Fatal error: Call to undefined method Joomla\Ldap\LdapClient::escape() in /var/www/html/portal/plugins/authentication/ldap/ldap.php on line 90

System information (as much as possible)

I noticed this difference without code from the ldap.php file from version 3.7.5 to 3.8.0 and I did not understand the error:

j!3.7.5, lines:
84 if ($bindtest)
85 {
86 // Search for users DN
87 $binddata = $ldap->simple_search(str_replace('[search]', $credentials['username'], $this->params->get('search_string')));
88
89 if (isset($binddata[0], $binddata[0]['dn']))

j!3.8.0, lines:
84 if ($bindtest)
85 {
86 // Search for users DN
87 $binddata = $ldap->simple_search(
88 str_replace(
89 '[search]',
90 $ldap->escape($credentials['username'], null, LDAP_ESCAPE_FILTER),
91 $this->params->get('search_string')
92 )
93 );
94
95 if (isset($binddata[0], $binddata[0]['dn']))

Additional comments

Basically, more parameters were added to $ binddata = $ ldap-> simple_search (
on line 87, the same happens for line 119 and 123 in j! 3.8.0
obs: Our portal is based on LDAP connection, all users use this authentication model, only super admin users who do not!
And even the super admin does not connect

Tanks!
