[Koha] Invalid value "0000-00-00 00:00:00" in field "borrowers.updated_on" with LDAP

[Michael Kuhn]

Hi

In an installation of Koha 24.05.03 I am successfully authenticating 
against an LDAP server which is writing the data of the authenticating 
user into the Koha database. But as soon as I search for the added user 
in the staff client I get the message: "500: Internal Server Error. 
Month out of range." This is because table field "borrowers.updated_on" 
is automatically filled with the value "0000-00-00 00:00:00".

I am aware of bug 
https://bugs.koha-community.org/bugzilla3/show_bug.cgi?id=31143 (We 
should attempt to fix/identify all cases where '0000-00-00' may still 
remain in the database) but of course it is not possible to manually 
change the value of field "borrowers.updated_on" from "0000-00-00 
00:00:00" to NULL every time a user successfully logs into the OPAC.

So I tried to set the value of "borrowers.updated_on" by using lines 
like the following, but unfortunately they all resulted in the invalid 
value "0000-00-00 00:00:00".

  <updated_on   is="">NULL</updated_on>
  <updated_on   is="potato"></updated_on>
  <updated_on   is="">2024-11-18 00:00:00</updated_on>

How can I prevent Koha filling in this invalid value when authenticating 
against LDAP and instead generate a NULL value?

Best wishes: Michael
