IMAP: multiple accounts on same server

[Ian Fitchet <idf@lunanbay.LESS-SPAM.com>]

Hi,

 I'm using Gnus v5.10.2 and have been playing with multiple accounts
 on my IMAP server.  My problem is that I've either misread the manual
 or can't access multiple accounts from the same IMAP server.

 If I set

(setq gnus-secondary-select-methods '((nnimap "imap.first.tld")
                                      (nnimap "imap.first.tld")))

 it obviously fails, well, it's not obvious but I guess Gnus reads
 that second nnimap entry as a cut'n'paste typo and ignores it.  If I
 set

(setq gnus-secondary-select-methods '((nnimap "imap.first.tld")
                                      (nnimap "imap-two" 
                                       (nnimap-address "imap.first.tld"))))

 Gnus, cleverly, determines that "imap-two" is just a reworking of the
 first select-method and, again, ignores the second entry.  However,
 having a second domain up my sleeve which is set up to have the same
 entries as the first domain, if I set

(setq gnus-secondary-select-methods '((nnimap "imap.first.tld")
                                      (nnimap "imap-two" 
                                       (nnimap-address "imap.second.tld"))))

 It works.  I get to login twice, can be two different users and
 select folders from both accounts.  Actually, it prompts me to login
 to "imap.first.tld" twice but we'll assume that's a DNS lookup issue.

 So, is there a neat way to say I want to login to an IMAP server to
 access multiple accounts without buying a domain name per account?

Cheers,
