Here they go attached.
Also, while googl'ing for this problem, it actually seems that it's the
libsasl circular re-entrance problem like the one also reported but for
libsasl 1.5
My conclusion is, if I remove those ldap entries from the nsswitch.conf
it all works good, if they're there, that's when problem occur.
Executing:
cyradm --user [EMAIL PROTECTED] deb
IMAP Password: at /usr/lib/perl5/Cyrus/IMAP/Admin.pm line 119
cyradm: cannot authenticate to server as [EMAIL PROTECTED]
Gives me:

Although I don't know if they're related.
