[imp] _prefs_hook_fullname

[Otto Stolz]

Hello,

since I have not yet received an answer on my general question
about programming Hook functions, I have tried my luck with a
simple (as I had hoped) example.

I am using Horde 3.1.2 and Imp H3 4.1.2. Configuration details
are appended, below.

I am trying to supply a sensible user name for the From headers
in outgoing mail, so I have adapted to our LDAP server the
2nd example for _prefs_hook_fullname from horde/config/hooks.php.
And I have modified the pertinent entry in horde/config/prefs.php
to read:
> $_prefs['fullname'] = array(
>     'value' => '',
>     'hook' => true,
>     'locked' => true,
>     'shared' => true,
>     'type' => 'text',
>     'desc' => _("Your full name:")
> );

Result: nothing; outgoing mail still has the header line:
> From: pop15959 at uni-konstanz.de

So, I put some debugging code into _prefs_hook_fullname.

Results:
- _prefs_hook_fullname is invoked only during
   Horde login, not during the subsequent Imp login.
- prefs_hook_fullname is invoked without an argument,
   the $imp array is NULL,
   and any and all of the following function calls yield NULL:
   · Auth::getAuth()
   · Auth::getCredential('user_name')
   · Auth::getCredential('username')
   · NLS::getCharset()
- consequently, _prefs_hook_fullname yields NULL.

So, what am I doing wrong?
And why is the preference for an e-mail parameter,
such as "user full name for From: line", in the Horde,
rather than the Imp, configuration?
And how should the Horde/Imp documentation be amended?

Thanks for any hint.

Best wishes,
   Otto Stolz
