Yes, it does! So we will wait for Koha revision 24.05.06 and then install it.

Meanwhile we implemented the following workaround in the crontab of Linux user "root" which sets the value of field "borrowers.updated_on" to NULL every minute if the current value is "0000-00-00 00:00:00":

* * * * * /usr/bin/mysql <databasename> -e "UPDATE borrowers SET updated_on = NULL WHERE updated_on = '0000-00-00 00:00:00';" &>> /tmp/bug36822-quickfix.log;

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
