The authentication message will contain an optional authorization
identity (authzid), the authentication identity (authcid), and the
password (passwd) [see RFC 4616].
Thus, there should be no problem in registering as name with nick name1
(this is the equivalent of doing /msg NickServ IDENTIFY <nick> <pass>)
I have just checked and freenode servers do support this use case.
The problem here seems to be that the nick renaming also changes the
nick used for sasl identification, while the nickname set by the user
should have been used for authentication.
