[turba] A few remaining issues with Turba

[Eric]

Thanks to you folks, I have almost gotten Turba running the way we need it 
to run.  There are just a few remaining problems I need to resolve.

I am using Horde 3.1.3 and Turba 2.1.2, the latest downloaded stable 
releases as of about a week ago.

MySQL is version 11.18 distribution 3.23.58, and the host is Fedora Core 2 
(old stuff, I know, but there is nothing I can do about it any time soon).

I have gone through the wiki and the mailing list archives and have not 
been able to find the answers.

PASSWORDS:  How to users change their own passwords?  I see how the 
administrator can do it for any user, but I don't see a way that users can 
do it for themselves.

GLOBAL ADDRESS BOOK:  I want the default address book (the one that is 
created when turba is first installed) to be available to everybody for 
reads, writes, edits, adds, and deletes.  I have use_shares set to true in 
sources.php (That was the default setting out of the box), and have checked 
all of the permissions boxes for each of the users under 
Administration->Permissions for the admin user, but users still can't see 
the admin's "My Address Book".

CREATING NEW ADDRESS BOOKS:  I can't find the way to do that.  Under 
Organizing->Address Book->My Address Book, it shows excerpts from the 
user's own My Address Book, but nothing is visible that would allow 
creating a new address book.

DATES:  Any dates prior to January 1, 1970, don't seem to get saved.  I 
have a "birthday" field that is set up in attributes.php to go all the way 
back to 1900, i.e.:

$attributes['birthday'] = array(
     'label' => _("Birthday"),
     'type' => 'monthdayyear',
     'params' => array(1900, null, true, '%Y-%m-%d'),
     'required' => false,
);

... but if I put anything in there with a date prior to the Epoch, it 
doesn't get saved.

Following is the applicable field description in turba_objects:

+-----------------+-------+------+-----+---------+-------+
| Field           | Type  | Null | Key | Default | Extra |
+-----------------+-------+------+-----+---------+-------+
| object_birthday | date  | YES  |     | NULL    |       |

I see from the mailing list archive that others had this same problem back 
in July / August but I was not able to find an answer in the archives.

Presumably it has something to do with the use of some time function 
somewhere that returns seconds since the Epoch, so that it doesn't know 
what to do with (or returns NULL for) times prior to the Epoch.

If that is something I have to live with, is there a supported ("right" vs 
"wrong") way to eliminate the year display altogether and just allow 
entering of the month and the day?

IMPORTING:  I realize this is a MySQL question and not a Turba question, 
but I assume many of you have been there and done that... Currently our 
address book is in an Excel spreadsheet.  I plan to export it to a CSV file 
and would like to import that file into Turba's turba_objects.  Can any of 
you suggest some reading for me to learn the right way (as contrasted with 
any number of "wrong" ways) to do that?

Thanks again for all your help...

Eric
