LDAP Configuration: ldap_connect() error

Hi,

I am having trouble with my LDAP configuration on my Suitecrm 8.2.2 installation. This is the error I’ve got:

[2023-01-18 01:57:53] php.WARNING: Warning: ldap_connect(): Could not create session handle: Bad parameter to an ldap routine {"exception":"[object] (ErrorException(code: 0): Warning: ldap_connect(): Could not create session handle: Bad parameter to an ldap routine at /var/www/suitecrm/vendor/symfony/ldap/Adapter/ExtLdap/Connection.php:151)"} []
[2023-01-18 01:57:53] request.CRITICAL: Uncaught PHP Exception Symfony\Component\Ldap\Exception\LdapException: "Could not set value "60" for option "network_timeout"." at /var/www/suitecrm/vendor/symfony/ldap/Adapter/ExtLdap/Connection.php line 106 {"exception":"[object] (Symfony\\Component\\Ldap\\Exception\\LdapException(code: 0): Could not set value \"60\" for option \"network_timeout\". at /var/www/suitecrm/vendor/symfony/ldap/Adapter/ExtLdap/Connection.php:106)"} []

My ldap configuration:

LDAP_HOST='ldap.xxxxxxx.net'
LDAP_ENCRYPTION='none'
LDAP_PROTOCOL_VERSION=3
LDAP_AUTO_CREATE=enabled
LDAP_PROVIDER_BASE_DN='cn=xxxx,ou=xxxxxxx,uid=michael@xxxxxxxx.net,dc=xxxxxxx,dc=net'
LDAP_PROVIDER_SEARCH_DN='cn=admin,dc=xxxxxxxx,dc=net'
LDAP_PROVIDER_SEARCH_PASSWORD='xxxxxxxx'
LDAP_PROVIDER_UID_KEY='uid'
LDAP_PROVIDER_FILTER='(&(objectClass=inetOrgPerson)(uid=michael@xxxxxxxxxxx.net))'

Thanks in advance.
