How hard would it be to automate step 4?

A quick update..
This was the process that worked for upgrading an existing 1.7 install using LDAP for authentication to 1.8

1. backup existing database and directory just in case
2. drop 1.8 code over top of existing code (for an upgrade you don't need the setup folder)
3. visit the install to test the basics are working ok via guest access e.g. create and test an LO
4. manually add the existing ldap details currently in the sitedetails table to the ldap table in the database
5. change from guest to ldap in config.php by commenting/un-commenting the relevant line
6. refresh index.php and test login via ldap

As I mentioned previously not sure if there's supposed to be an automated way of transferring ldap details from the sitedetails table to the ldap table?

The other thing I'm not sure about is that the ldap table contains ldap_knownname as a field that can't be empty and is created by basic.sql in a new install and also exists in a 1.7 install yet I can't find anywhere ldap_knownname is used in either 1.7 or 1.8 code. Should this be removed from basic.sql?

Yep. But we need to make this easy, otherwise people are going to get in a mess / screw up their installs.

Hi Julian
yes I can see it cropping up regularly once people start trying to upgrade as opposed to a new install. But at the moment I don't have the answers to my two questions and especially question 1.

Not sure if perhaps 1.8 code should look in sitedetails as well as the ldap table for existing installs or if upgrade.php isn't working as it should. Not even sure if upgrade.php is meant to achieve this transfer of ldap info from sitedetails to ldap? On a new install the values added during install or via management.php go into the ldap table but not sure what's supposed to happen for existing installs?

In 1.8 /library/xerte/authentication/ldap code the note says:

* For this to work, you'll need to have at least one entry in the XOT 'ldap' table.

What is supposed to happen for existing installs where the ldap values are in sitedetails and also some field/column names differ?

I guess these are questions for David or Pat or perhaps Thomas has encountered/resolved this too?

Ron, would you mind documenting this process thoroughly, as you find out how to do it, because this is going to come up a lot. If we get one good, thorough set of instructions it will save us a load of pain. Maybe there is an upgrade script or something we could write?

Thanks,

Julian

Hi all
I had a chance to test an upgrade to 1.8 of a previous 1.7 install which uses ldap today. The previous and working install had the ldap values in site details rather than the separate ldap table.

Upgrade process:
drop code over top
this then defaults to guest access but useful for checking the basics work
change from guest to ldap in config.php by commenting/un-commenting the relevant line
refresh index.php and try to login via ldap
get error message LDAP servers not configured in DB
visit management.php and check - ldap details displayed but not saved to ldap table in db - clearly coming from site-details
try running upgrade.php indicates nothing to upgrade

Questions:
1. what's the process for transferring the ldap details from site_details to ldap table for an existing install?
In this case I can enter direct in the db but that's surely not the intended method?

2. In the ldap table what typically goes in ldap_knowname?

Cheers
Ron
