I tested mbsync
which version?
with Microsoft Outlook using custom Entra IDs and ran into
trouble until I increased the size of the SASL and vprintf buffers,
commit a846ab0 included in v1.4.3 should have solved the problem with
ever-growing sasl tokens for good.
are you sure you tested the unpatched version you built from source?
+++ b/src/drv_imap.c
- char saslmechs[1024], *saslend = saslmechs;
+ char saslmechs[16384], *saslend = saslmechs;
this has absolutely no effect on the supported token size.
+++ b/src/util.c
-# define QPRINTF_BUFF 1000
+# define QPRINTF_BUFF 16384
this also shouldn't be relevant.
if you are positive that either hunk is actually required, then please
post (or mail me) the -Dn output of the authentication sequence.
