i'm working with sasl binding to my ldap server.  is there some way i can override where the sasl "EXTERNAL" method is looking for the TLS_CERT and TLS_KEY directives?  i'm basing this on a per-machine basis and serveral services will be using the library so it doesn't make sense to have each service run as a seperate user and different ldap certs on the machine.

thanks,

wyatt
