Hello I ask this question a long time ago but had no time until now. Here is a snip of the conversation: [snip] ... 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@xxxxxxxxxx" 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@xxxxxxxxxxxxxxx" 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. > > the Hostname of the Source-Server. Or change sasldb after copying. Or... > > ... what you mean with "change sasldb after copying"? Do something by hand? 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. [snip] 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?
