Re: saslauth configuration question - ANSWERED

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]


Thanks I see the light,

OK, I'm defiantly using sasldb and saslauthd because it is the only source of
user and pass word (no user account on the server).

When there is failure this /var/log/maillog message or something like it:

AUTH failure (DIGEST-MD5): user not found (-20) SASL(-13): user not found: no
secret in database

A google of the above is often answered with something like "which database?
Ah... that's the question"

Charles Bradshaw says: "Look in your syslog for further clues" you should see:
 unable to open Berkeley db /etc/sasldb2: No such file or directory <<<<< THIS
SHOULD BE IN maillog as well please.
 no secret in database <<<<< This is duplicate in maillog


Just the latter which means the user and/or realm and password details are not
in sasldb2. Why is sasldb2 being accessed? read on...

Clearly I DON'T KNOW that's why I ask the question!

Charles Bradshaw says: Answering questions with questions and/or re-iterating
quotes from other (potentially misleading) sources is just noise and serves
only to increase my depth of confusion.

I hope this helps others, thanks Charles Bradshaw
