Move sasldb2 between two servers

[Martin Schweizer]

Hello

I ask this question a long time ago but had no time until now. Here is
a snip of the conversation:

...

An entry in sasldb contains 3 or maybe 4 parts. Username, Realm, Password (and
Type: the "userPassword"). If your users uses only a Username, without
@domain-Part, the Hostname of the Server is used for this key. This is
servername in imapd.conf for Cyrus-Imapd.

Either create entries with:

# saslpasswd -cu domain.tld username

And tell your users to use "user at domain.tld" as Username. This should work on
both servers, then.

Or if you (have already) create(d) entries with:

# saslpasswd -c username

The Hostname of the Server is used and either your Users use
"username at host.domain.tld" as username or you have to change something
between the Source and Destination (Backup) Server. The easiest is to change
the servername (imapd.conf) of the Backup-Server to be equal the other. Then
Users can use "username" on both servers.

If the databasetype is bdb, you can use db_dump/db_load

# db_dump -p /etc/sasldb2 | sed 's/host1\.domain\.tld/host2.domain.tld/' |
db_load /etc/sasldb2_new

This is only an example, if you really want to use something like that, you
should work at least on the regexp in sed.

Or a little Perl-Script.

I have two cyrus mail server with exact the same setup which runs in a
master/slave syncroniation. It works perfect. The problem is I need to
update both sasldb2 files if I get a new user. As you can read above
there are some solutions. In my environment the

# saslpasswd -cu domain.tld username

is the best way because I have only about 30 users. I tested the above
but could not authentication correct. What do I wrong?

Kind regards,
