Successfully installed Moodle 1.8. Colleague created exam questions as admin user. Upgraded successfully? to Moodle 1.9 beta4 for extra features (larger fields for certain question types). After some time, admin required to login again. login/index.php click on browser (IE, Opera and Firefox tried by colleague - obvious that was not a browser bug) led to browser interrupting a "redirect storm" (see tcpdump extracts below).
First-time moodle user/admin so would appreciate any pointers to look in database and/or code where this fault may be originating from.
Diagnosis steps:
1) tcpdump (complete supplied/generated on request)
sample packets:

Module was not the problem.
Ran this query:
mysql> select * from mdl_config where value like '%iped%';
which reported (among other rows):
| 127 | alternateloginurl | http://iped-editors.org/moodle/mod/resource/view.php?id=13 |
Which looked suspiciously like the culprit.
ran this:
mysql> update mdl_config set value = NULL where id = '127';
And login works!
Now to find out how this got set in the first place.

This is set in Admin->Users->Authentication->Manage Authentication - it would seem that someone set this value - possibly as part of the resource modification you were doing?

Thanks Matt.
That would make sense. I suspect that is what the admin did.

After installing 2.0.2 and setting it up, I experience the same problem.
The solution described here worked for me, too! Thanks a million!
It seems that problem was cause by acitivating the e-mail registration plugin.
