Commit a5bcfe6 removed an optimization that fetches the default group from the current user token, as it is sometimes not accurate such as when groups like the builtin Administrators group is the primary group. However, removing this optimization causes extremely poor performance when connected to some Active Directory environments. Restored this optimization as the default behaviour, and added a `group: db-accurate` option to `nsswitch.conf` that can be used to disable the optimization in cases where accurate group information is required. This fixes git-for-windows/git#4459 Signed-off-by: Richard Glidden <richard@glidden.org>

A recent commit removed an optimization from the Cygwin runtime that fetches the default group from the current user token: At times, this is not accurate such as when groups like the builtin Administrators group is the primary group. However, removing this optimization causes extremely poor performance when connected to some Active Directory environments. Reflecting git-for-windows/msys2-runtime#57, this update restores this optimization as the default behaviour. To still allow the user to opt into the correct behavior, a `group: db-accurate` option is provided for `nsswitch.conf`. This fixes git-for-windows/git#4459 Signed-off-by: Johannes Schindelin <johannes.schindelin@gmx.de>

There was a problem hiding this comment.
Since we do not build the documentation, this can easily be done in a (non-critical) follow-up PR. @placaze how about it?
