plugins/sql.c does:
if(sparams->user_realm) {
user_realm = sparams->user_realm;
} else {
user_realm = sparams->serverFQDN;
}
Where user_realm would represent the sasl realm derived from the sasl
mechanism used. I don't believe either LOGIN or PLAIN support the passing of
a sasl realm, or generate one.
serverFQDN represents the value passed to sasl_server_init, which in
imap/imapd.c is:
if (sasl_server_new("imap", config_servername,
NULL, NULL, NULL, NULL, 0,
&imapd_saslconn) != SASL_OK) {
config_servername is generated from :
lib/libconfig.c:
/* look up the hostname and info we should present to the user */
config_servername = config_getstring(IMAPOPT_SERVERNAME);
if (!config_servername) {
config_servername = xmalloc(sizeof(char) * 256);
gethostname((char *) config_servername, 256);
}
You should be able to set a 'servername' value in imapd.conf to essentially
hard code a value for %r. It may make more sense to disregard %r
altogether, and get your domain information from %u.
