Unable to connect to your database server using the provided settings

Hi,

I'm getting that standard error that happens when there's something wrong with the sqlsrv driver specifications.



It's php 7.1:


Unable to connect to your database server using the provided settings.

Filename: C:/.../system/database/DB_driver.php

Line Number: 436


My database.php array is

$db['default'] = array(

'dsn' => 'sqlsrverver=myserver;Database=mydatabase',

'hostname' => 'myserver',

'username' => '',

'password' => '',

'database' => 'mydatabase',

'dbdriver' => 'sqlsrv',

'dbprefix' => '',

'pconnect' => FALSE,

'db_debug' => (ENVIRONMENT !== 'production'),

'cache_on' => FALSE,

'cachedir' => '',

'char_set' => 'utf8',

'dbcollat' => 'utf8_general_ci',

'swap_pre' => '',

'encrypt' => FALSE,

'compress' => FALSE,

'stricton' => FALSE,

'failover' => array(),

'save_queries' => TRUE
);


I tried with and without the dsn specifiied.

My server is configured for Windows Authentication.  And And I'm able to connect outside of this Codeigniter project.

My thread-safe dll in extensions and php.ini is php_sqlsrv.dll


What else should I look for, in order to track this down?
