Hi folks.

I've installed PHP 8.0 on my server, and just installed php-ldap. All 
looks to have worked fine.

php-common-8.0.28-1.el7.remi.x86_64
php-8.0.28-1.el7.remi.x86_64
php80-php-common-8.0.28-1.el7.remi.x86_64
php80-php-ldap-8.0.28-1.el7.remi.x86_64
php-cli-8.0.28-1.el7.remi.x86_64
php-sodium-8.0.28-1.el7.remi.x86_64
php80-runtime-1.0-3.el7.remi.x86_64

However, when I try to  use LDAP in a script, it says the ldap_connect 
function is not available:

[root at testsvr ~]# ./ldapAuth.php gary.stainburn fake-password
PHP Warning:  PHP Startup: Unable to load dynamic library 'ldap' (tried: 
/usr/lib64/php/modules/ldap (/usr/lib64/php/modules/ldap: cannot open 
shared object file: No such file or directory), 
/usr/lib64/php/modules/ldap.so (/usr/lib64/php/modules/ldap.so: cannot 
open shared object file: No such file or directory)) in Unknown on line 0
PHP Fatal error:  Uncaught Error: Call to undefined function 
ldap_connect() in /root/ldapAuth.php:12


Can anyone see what I've missed?
