Hmm... It looks mostly alright, except one thing. I'm not
familiar with cdb lookups, but I believe they should be generally
the same as dbm lookups. In this case, if the text file from
which you build the cdb file has entries such as:

user:alias    thingie


then the key will be "user" and the data will be "alias    thingie",
and _not_ "user:alias" and "thingie", which, as far as I
understand, is what you're trying to achieve.

Ah. I didn't know this. So, yes, Philip seems to know what he's
talking about ;) The botton line is that this is probably the
problem, but the ":alias" thingie is probably another problem.
