[horde] mcrypt, mssql, & login problem

[Garrett Davis]

I need some clarifications due to conflicting statements on horde.org

1.  Is mcrypt required?
2.  Is MS SQL supported?

Using MS Win2k Pro
IIS 5.0
MSSQL 2000
PHP 4.2.3 (CGI)
Horde 2.1

Test.php reveals:
All good except:
MCAL Support:  No
Mcrypt Support: No

When attempting to login to horde, I am immediately returned to the login
screen with no error. Log
reveals this entry:

Sep 17  HORDE [error] [horde] FAILED LOGIN for garrett [127.0.0.1] to Horde
[on line 43 of "C:\Inetpub\wwwroot\BTHwebs\horde\login.php"]

Password has been md5'd in the db.

horde.php=

$conf['auth']['driver'] = 'sql';
$conf['auth']['params'] = array();
$conf['auth']['params']['phptype'] = 'mssql';
$conf['auth']['params']['hostspec'] = 'localhost';
$conf['auth']['params']['username'] = 'horde';
$conf['auth']['params']['password'] = 'xxxxx';
$conf['auth']['params']['database'] = 'BTHwebs';
$conf['auth']['params']['table'] = 'horde_users';

$conf['prefs']['driver'] = 'sql';
$conf['prefs']['params'] = array();
$conf['prefs']['params']['phptype'] = 'mssql';
$conf['prefs']['params']['hostspec'] = 'localhost';
$conf['prefs']['params']['username'] = 'horde';
$conf['prefs']['params']['password'] = 'xxxxx';
$conf['prefs']['params']['database'] = 'BTHwebs';
$conf['prefs']['params']['table'] = 'horde_prefs';

php can successfully connect to mssql with the above
data using mssql_connect()

Does the password above in horde.php need to be md5'd?
I haven't tried that.

I've been trying to correct for a couple days with no luck.

Please Help.
