Title: LDAP Active Directory Primary Groups support depends on bcmath module

At least in Debian based distributions (Ubuntu) it is compiled into PHP, but it is a dedicated package on OpenSuse for instance. Before using bc math functions a check is done, if they are not present a log message is written, beside this ownCloud continues to work, only this feature does not.

i need to test it further myself, but others are welcome of course, too.
