[SM-PLUGINS] Change SQL Password plugin problem

[Alejandro F. <ale...@ya...>]

Dear all, I have Debian Etch + Postfix + Courier + MySQL + Squirrelmail 
as my mail server platform.

I need to install the change SQL password plugin in order to let users 
change their password themselves. So I went to the plugin section to 
choose the appropriate one. The newest change_mysqlpass plugin is 
version 3.3-1.2 and it needs the compatibility plugin 2.0.4 and Pear DB 
Library. But compatibility 2.0.4 needs to install a patch to the 
squirrelmail source code, but I have the Squirrelmail 1.4.9 debian 
package so I don't have the source code. I can't choose this plugin version.

After that I installed the change_mysqlpass 3.2 (an older version) and 
compatibility plugin 1.2 (both from April 2003). After installing and 
configuring the plugins and config.php file with the corresponding MySQL 
DB values, I add these plugins to the Squirrelmail using the conf.pl 
menu, and after that I log into the webmail but I see this warning:

**Warning*: mysql_result(): supplied argument is not a valid MySQL 
result resource in 
*/usr/share/squirrelmail/plugins/change_mysqlpass/functions.php* on line 
*129**

After thay I try to change the SQL password and I SUCCEED.

What can be the cause from this warning message at the webmail account ???

If it is a plugin version problem, how can I upgrade the plugins if  I 
use squirrelmail 1.4.9 debian package and so can't apply a patch to the 
source code ??? Because I wan't to maintain the debian package and not 
to install the last squirrelmail tarball version.

Thanking in advance,

Alejandro
