I got the same problem. It is related to changes from php5 to php7 as far as I can see. The Ubuntu package is a ldap-account-manager version 5.2 where the statement for ldap-account-manager 5.3 is "LAM 5.3 with PHP 7 compatibility".
Actually I got several problems after upgrading from Ubuntu 14.04. To test it had nothing to do with the upgrade process I also tried it out on a completely clean server install and the ldap-account-manager was not working at all. I have tried to build a new package based on the ldap-account-manager version 5.5 and it seems to work so far. I did add php-xml and php-zip to dependencies. I have also install libapache2-mod-php which seems to be needed now, but I am not quite sure how to add that properly as dependency. I considered trying the deb package from the ldap-account-manager site but I was not quite sure if it handled the installation in the same way as the ubuntu package. There I choose what to me seemed the fast and safe way of making a new ubuntu package based on the ubuntu package for 5.2 and the new upstream source for 5.5. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1632193 Title: Editing of LDAP users causes blank screen To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ldap-account-manager/+bug/1632193/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
