X-Git-Url: https://git.internetallee.de/?a=commitdiff_plain;h=460ab097380d81bd531a21c2ec192941b2268e4f;p=horde.git

Use an array_key_exists() call here instead of empty() to support searching for empty userIds

System shares will have null owners so tags on system shares will have an empty tag user.
