Maybe it's the same patch than in RedHat. There the issue is that cyrus
configuration code is separated in 2 parts: one in the core library
(pretty much static; values accessed with
libcyrus_config_getxxx/libcyrus_config_setxxx), the other being
accessible in all services and populated from the content of imapd.conf
(values accessed with config_getxxx).
The patch declares the option in both parts and uses
libcyrus_config_getxxx to query the value because it is needed in the
core library. From what I could see, what is lacking is a line of code -
usually in imap/global.c:cyrus_init - do get the value from imapd.conf
and set it in the core library, like it is already done for some other
options. Example with username_tolower:
libcyrus_config_setswitch(CYRUSOPT_USERNAME_TOLOWER,
config_getswitch(IMAPOPT_USERNAME_TOLOWER));
I don't know who is in charge of this patch, but maybe Jeroen can help
fix the issue on RedHat side. Actually he seems also linked to the patch
on Debian ?
