LDAP Guest Login - Help UrgNT

[vijay]

I am authenticating a web application using LDAP. I am using
a .htaccess to perform this task. I am pasting the htaccess file
content here:
<-----
AuthName "CEC"
AuthType Basic
LDAP_Server ldap.mycompany.com
LDAP_Port 389
Base_DN "ou=active,ou=employees,ou=people,o=mycompany.com"
UID_Attr uid
require valid-user
----->

I want to give access to a new user who is not in LDAP. At the same
the LDAP users should be able to use this. This means, in addition to
the existing set of LDAP users I want to add a new dummy user. I also
want to provide a dummy password for the new user. How can i do this?
Please help me.

This is an urgent requirement.
