LDAP Configuration - Use form submitted credentials as browse credentials

I'm in the processing of configuring LDAP integration with TeamCity and I'd like to avoid putting an LDAP user account password (scrambled or otherwise) into a properties file. 

Is it possible to use the form-submitted user credentials to as the credentials for browsing? Something like:

java.naming.security.principal=DOMAIN\\$login$
java.naming.security.credentials=$password$

It doesn't look like TeamCity does the $login$ or $capturedLogin$ string replacement on principal or credentials though.. 

Is this possible at all?

Thanks,

Pete
