Common
...
Errors
...
The
...
various
...
errors
...
encountered
...
in
...
the
...
use
...
of
...
Shibboleth
...
are
...
primarily
...
categorized
...
by
...
the
...
location
...
they
...
are
...
reported.
...
From
...
there,
...
errors
...
are
...
generally
...
listed
...
by
...
system
...
or
...
by
...
exact
...
phrase.
...
These
...
phrases
...
are
...
then
...
routed
...
to
...
one
...
more
...
layer
...
which
...
suggests
...
specific
...
problems
...
that
...
may
...
cause
...
each
...
error
...
and
...
solutions
...
to
...
those
...
problems.
...
Note
...
that
...
most/all
...
of
...
the
...
browser
...
errors
...
will
...
also
...
show
...
up
...
in
...
log
...
files,
...
and
...
that
...
recent
...
versions
...
of
...
Shibboleth
...
may
...
not
...
come
...
with
...
error
...
templates
...
that
...
will
...
display
...
the
...
error
...
message
...
to
...
the
...
browser,
...
as
...
a
...
protection
...
against
...
scripting
...
injection.

Errors

will

usually

show

up

more

generically

in

the

than

in

the

combination

of

the

should

the

Common Problems
Some stuff that a lot of installers run into:
- IdPWontStart: The IdP won't start up (you get a 404 or Resource not Available from Tomcat)
- SPWontProtect: The SP just ignores you and lets requests pass on through
- SPEmptyHeaders: The SP doesn't appear to be exporting the attributes as expected
- TomcatOutOfMemoryError: The IdP 1.3 seems to produce a memory overhead and Tomcats hangs up with an Out of Memory exception..
