[Dovecot] auth protocol, buffers

Hello Timo,

I'm curious about 2 points (I'm using alpha2 but these are general questions) :

Background :

. I connect to dovecot-1.0.alpha2 through thunderbird . I use ldap pass/userdb and PLAIN mech . I've only got one auth block in dovecot.conf (all pass/userdb/mech except ldap/PLAIN are commented)

1. I notice that, for one thunderbird connection trial, imap-login issues 2 AUTH messages. Why ? What info does the "resp=" hold the second time ? It goes like this :

Info: Dovecot v1.0.alpha2 starting up
Info: auth(default): client in: AUTH   1       PLAIN   service=IMAP     lip=xxx.xxx.xxx.xxx        rip=xxx.xxx.xxx.xxx
Info: auth(default): client out: CONT  1
Info: auth(default): client in: CONT   1       AGRvdmV0ZXN0AGZvbw==
Info: auth(default): ldap(dovetest,xxx.xxx.xxx.xxx): base=ou=personnes, dc=pasteur, dc=fr scope=subtree filter=(&(objectClass=posixAccount)(uid=dovetest)) fields=uid,userPassword
Info: auth(default): ldap(dovetest,xxx.xxx.xxx.xxx): userPassword(password)={CRYPT}sa8ufSVwLUHVU uid(user)=dovetest
Info: auth(default): client out: FAIL  1       user=dovetest
Info: auth(default): client in: AUTH   2       PLAIN   service=IMAP     lip=xxx.xxx.xxx.xxx        rip=xxx.xxx.xxx.xxx        resp=AGRvdmV0ZXN0AGZvbw==
Info: auth(default): ldap(dovetest,157.99.64.42): base=ou=personnes, dc=pasteur, dc=fr scope=subtree filter=(&(objectClass=posixAccount)(uid=dovetest)) fields=uid,userPassword
Info: auth(default): ldap(dovetest,157.99.64.42): userPassword(password)={CRYPT}sa8ufSVwLUHVU uid(user)=dovetest

dovecot: Sep 20 17:58:27 Info: auth(default): client out: FAIL 2 user=dovetest

2. Which buffer/string handling function (among those in your lib) should I use to safely allocate a string and/or copy a string into another ? (instead of using str[n|l]cpy for instance) ?

Thank you.
