sdap: properly handle binary objectGuid attribute Although in the initial processing SSSD treats the binary value right at some point it mainly assumes that it is a string. Depending on the value this might end up with the correct binary value stored in the cache but in most cases there will be only a broken entry in the cache. This patch converts the binary value into a string representation which is described in [MS-DTYP] and stores the result in the cache.

Replace space: add some checks This patch adds some additional checks if the option for replacing spaces in user and group names is used. When replacing space with the replacement character it is checked if the name already contains the replacement character. If it does the unmodified name is returned because in this case a revers operation would not be possible. For the reverse operation is it checked if the input contains both a space and the replacement character. If this is true the unmodified name is returned as well, because we have to assume that it is the original name because otherwise it wouldn't contain both characters. Additionally a shortcut if the replacement characters is a space and tests for the new checks are added. The man page is updated accordingly.
