Hello, my IdP is kind of progressive and implemented RFC9068, where all access tokens now come with typ "at+JWT". Since the setup has used local validation, I had to switch and currently use introspection endpoint. Looked around at the src and there seems to be relatively simple check of the token typ checking the only fixed value of "JWT" -- do you think you could consider tuning it a little...

..."); ``` I then use passthrough events like the following: ``` e_debug(event_create_passthrough(data->event)->event(), "Modified mailbox_list_iter_init was called."); e_warning(event_create_passthrough(event)->event(), "Did not find required key 'roles' in the JWT body."); ``` `e_warning` and `e_error` work fine. If I understand the documentation for the unified event filtering (https://doc.dovecot.org/configuration_manual/event_filter/#unified-filter-language) correctly, I should be able to enable debug logging for with `log_debug = event="oidc_s...

In a Box and Whisker plot, I thought that when there are outliers both abov= e and below the whiskers, then the whiskers should both be the same length = (plus or minus 1.5 times the inter-quartile range). If you look at the plot for SilwoodWeather on p.155 of The R Book you will = see that for November (month =3D 11) the upper whisker is shorter than the = lower, while for other months with

Hello, Over the last 12 hours or so, I've been wrestling with a mysterious dovecot issue. After upgrading a mail server I'm helping my friend with maintaining from Fedora Core1 to Fedora Core4, I realized that I couldn't use UW-IMAP4 anymore (well, I can compile it myself, but it turned out that UW-IMAP was the main cause of the server's having load average as high as 30 from
