Thanks! Following yfastud suggestion of using IIS with horde docs as a guideline and diddling with the right php.ini (the one apache2 uses) I was able to get the basics of horde and gollem to work. Also the with help of horde/gollem included docs.
Wampserver2 was helpful in enabling the correct PHP extension via the tray icon.
Another handy thing was using the horde supplied test.php (e.g. [
localhost]) for trouble shooting config issues.
There is still more to do like configuring login stuff like LDAP and kerberos but there has been forward momentum.
Thanks again.
