Getting message "SASL Could not open /etc/sasl2/sasldb2" when trying to create a mailbox

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


We have a server which, among other things, runs an email service for our company. This server runs RHEL 7.9, Cyrus and Sendmail.

Now we are replacing the hardware of this server and I am configuring the new server with RHEL 9 and the correspondingly new versions of cyrus-imapd (3.4.1-7.el9), cyrus-sasl (2.1.27-20.el9) and sendmail (8.16.1-10-el9).  I am not copying over configuration files but editing the new files to replicate the function of the production server.

I have encountered difficulties with getting the Cyrus IMAP service working.  There are a number of messages in /var/log/maillog which hint that Cyrus cannot access the SASL password database (/etc/sdsl2/sasldb2) but I am very confused about this sequence of symptoms and cannot pose a coherent question to you.

A simpler problem, which may turn out to be primary, is that I cannot create an IMAP mailbox for any user.  My steps are:

1) "cyradm -u cyrus localhost"
2) Enter password for cyrus account  (previously created with saslpasswd2 and verified with sasldblistusers2)
3) "cm user/dale"
4) Output on terminal "createmailbox: System I/O error"
5) Output in /var/log/maillog

Nov 24 14:25:38 localhost cyrus/imap[2989]: IOERROR: mkdir failed: fname=</home/imap/d/user/dale/cyrus.index> syserror=<Permission denied> func=<mailbox_create>

There seems to be two problems here, a failure to access the SASL database and a failure to create the mailbox caused by "Permission denied".  In other tests I changed the permission on /home/imap to allow anyone to write but still I get "Permission denied".  I have also changed the permission on /etc/sasl2/sasldb2 to allow anyone to read. In either test the failure persists.

I have done a lot of searching the Red Hat Knowledge as well as general Google searchs.  I have found some sites where people are asking about these particular log entries, but I have not seen one with a useful response.  Generally there is simply no reply.

Below I have "sasl_pwcheck_method: saslauthd".  I have also tried "auxprop" but authentication continued to fail.

Your help would be appreciated.

Both the Cyrus and SASL daemons are running.
