4.2.0 to 4.2.1c to 4.5 **HELP!?**

[mpietersen]

Hello, I'm trying to upgrade my SugarCRM suite to version 4.5,but am having some problems getting there.

My system is running;

FC4
PHP 5.0.4
Mysql 4.1.20
/var/www/html (chmodded 777)

Version 4.2.0 has been running very well for us for the past 6 months since implementation, but we would like to upgrade the version to stay up to date and add some features available in the new release.
After upgrading to 4.2.1c I get an error when trying to access certain areas of Sugar.

When trying to access My Account, Admin, and Logout, I get 'Not a Valid Entry Point'. I have tried to add 'if(!defined('sugarEntry'))define('sugarEntry', true);' to the PHP forms that I believed to be responsible for these areas of Sugar, but have not restored any functionality. I have checked the PHP forms for the 'if(!defined('sugarEntry') || !sugarEntry) die('Not A Valid Entry Point'); ' and it is current with the new method of entry point validation.
I have searched for this problem, and haven't gotten too much information back from it.

At this point I'm stuck. I don't know a TON about linux, and I'm not sure whats holding back SugarCRM from going further. There is no 4.2.0 - 4.5 patch, so I have to make this upgrade work to progress any futher.

HELP!
If you guys need anymore info, let me know and I'll do the best I can to provide anything else.

Thanks,
-mike

Okay, I've made a bit of progress by myself.

Initially the server was set up using;
Sugar 4.0.1
Admin Modules
LDAP 0.7.3 patch

Later my boss updated to 4.2.0 and LDAP 0.8.3 which worked fine.
This is currently what we have deployed corporate wide.

Now, in order to get mine working I had to back track in certain steps.
If you take the logical upgrade path, and continue to update with the patches, you will end up breaking the Sugar install. Don't ask me what breaks, but you end up getting the "Not a valid entry point" error that I described in my inital post.

What I did to bypass the error is remove all instances of SugarCRM after backing the SQL tables.
After doing a install based on the 4.2.0 package and reloading the mysql database, the server complained about missing files (and also gave the location of the files that it was looking for! AH HAH.)

I placed the missing Admin Module, LDAP patch, and 4.0.1 to 4.2 patch in the appropriate places, the patch to 4.2.1c now happily installs. No errors, no complaints! After making the 4.2.1c patch, I then patched to 4.5 and this worked aswell.

Now, the only thing left is to try and figure out why my AD isn't authenticating.
