If the path to complete begins with ~, that's indeed the purpose.

However, your problem is not specific to bash completion: if every call 
to some NSS function, such as getpwent(), triggers an LDAP request, 
you'll have exactly the same result running 'ls -l' in any directory. 
And you'd better configure local caching to avoid overriding your 
network and your ldap server.
