[Dovecot] BUG: LDAP extension failed to authenticate if 'base' DN configuration is empty ''

[Hendy Irawan]

Dear Timo,

Thank you very much for your kind work.

I apologize, my previous statement were wrong. At least on ApacheDS 1.5.7,
it doesn't search entries using the '' base DN (it doesn't give error
though, just cannot return results, ApacheDS requires the search base to be
in a partition).

However, your patch would be great for servers who support the '' search
base DN.

If I may ask, would you improve it further to accept multiple bases? I'm not
sure what the proper character separator would be, but I think something
like this would work :

base = dc=prd,dc=berbatik,dc=com | dc=stg,dc=berbatik,dc=com

The proposed configuration above asks to try the two search bases in
succession, whichever first succeeds get logged in, else fails like usual.

I hope it's okay with you. I'll definitely help with the testing.

Hendy
