We have a similar setup with AD authentication and DB as a backup. I have the DBIdentityLoginModule configured with the options of:
<module-option name="hashAlgorithm">MD5</module-option> <module-option name="hashEncoding">HEX</module-option>
I believe these are the defaults for this module.
Thanks for your reply.
I actually tried this scheme and it failed. However, as you suggested it again I gave it another whirl and found I have some other problem, as the password was being validated.
Thanks for your help.
