Error performing SASL authentication step: SASL(-1): generic failure: Unable to find a callback: 32775

[Tamas P. <tk...@gm...>]

I have just switched from Debian to Fedora, and I am trying to get
e-mail working with mbsync, 1.5.0 (but I also get the same error with master).

The relevant excerpt from my .mbsync (the whole config used to work, and
is unchanged) is

IMAPAccount ihs-account
Host outlook.office365.com
User "tp...@ih..."
PassCmd "/home/tamas/bin/oauth2ms"
AuthMechs XOAUTH2
TLSType STARTTLS
# Increase timeout to avoid o365 IMAP hiccups
Timeout 120
PipelineDepth 50

The relevant oauth2ms script above works fine, insofar that it spits out
a token.

Then running mbsync -V ihs I get

Reading configuration file /home/tamas/.mbsyncrc
