Hello,


this is correct.
But isn't horde/passwd supposed to replace the placeholders with the
actual values?

SQL logging won't help here since it will just show that the values are
missing - as does the horde log...


So my question is:
What could cause horde/passwd not to expand the %u and %p placeholders
in backend.conf?
