Excellent points. Hmm. In that case, maybe we just need: ``` # Set the server-side preferred DH group size, in bits SFTPDHGroupPreferred 2048 ``` and forego the min/max limits. Although,...

The stock `sftp` clients often only use SFTP protocol version 3; UTF-8 support is only officially supported for SFTP protocol version 4 and later. However, you _can_ use the [`SFTPClientMatch`](http://www.proftpd.org/docs/contrib/mod_sftp.html#SFTPClientMatch)...

Can you provide the bad/non-working ProFTPD configuration (minus passwords) that you were using, so that I can reproduce the bad behavior locally, and see how it can be best improved?...

I think you may need to put this block: ``` UserOwner main1 GroupOwner main1 ``` inside of your `` section; I suspect that when you login as user "system1", it...

Per the [`IgnoreHidden`](http://www.proftpd.org/docs/modules/mod_core.html#IgnoreHidden) docs, you also need to use one of the following directives _as well_: * [`HideFiles`](http://www.proftpd.org/docs/modules/mod_core.html#HideFiles) * [`HideGroup`](http://www.proftpd.org/docs/modules/mod_core.html#HideGroup) * [`HideNoAccess`](http://www.proftpd.org/docs/modules/mod_core.html#HideNoAccess) * [`HideUser`](http://www.proftpd.org/docs/modules/mod_core.html#HideUser) These various `Hide*` directives say which...

What does [ProFTPD debug logging](http://www.proftpd.org/docs/howto/Debugging.html) (different from trace logging, and the SFTP module logging) show, for both the success and failure cases? I suspect that the trailing space is a...

Can you try a newer version of ProFTPD, e.g. 1.3.6, or the `master` branch on GitHub?

It's possible that this is a duplicate/symptom of Issue #656; using the latest ProFTPD code from the `master` branch on GitHub can confirm if this is the case.

Does this work as expected, if you (temporarily) disable the `mod_vroot` module?

I believe this might be the same issue as https://github.com/proftpd/proftpd/issues/1325. Would you be able to use a newer ProFTPD version, such as 1.3.8rc3?
