Question is getting a bit old, but here's an answer. There are some junk files in the template directory that the software is trying to read in. Try removing the files and I'd bet it will work
rm -f /var/hda/web-apps/phpldapadmin/html/phpldapadmin/templates/creation/._*
rm -f /var/hda/web-apps/phpldapadmin/html/phpldapadmin/templates/modification/._*
I used to have these sorts of hidden files pop up all the time when editing files from a Windows share on my Mac. Not sure if you've got anything similar going on or not...
