While POP works fine, we are seeing authentication failures through Perdition to the Courier IMAP, as shown below.  I see there was a similar issue reported in build 1.18, in early 2011, but it was thought to be fixed since then.

Hi Todd,

I have taken a closer look into this but unfortunately I have drawn a blank,
the sequence below seems to work for me. Could you let me know
which version of Courier IMAP you are using. My test environment was:

Debian Testing (amd64)
* From the courier 0.66.3-2 source package
  + courier-base 0.66.3-2
  + courier-imap 4.9.3-2
* From the courier-authlib 0.63.0-4 source package
  + courier-authdaemon 0.63.0-4
  + courier-authlib 0.63.0-4
  + courier-authlib-userdb 0.63.0-4
