I see. To be honest, I'm a bit overwhelmed with the complexity of Samba 
but, the more interesting it will be to understand all of this.

In general, there is much of an interest around me to move away from 
Windows to Linux-only environment, keeping all the AD-based 
infrastructure in the "just working" state. This is perfectly doable 
with Samba, except that support for 2012R2 level is required by the 
customer. One of the features missed was "KDC resource groups 
compression". Now, version 4.19 will hopefully fix it, but the status of 
SID history compression is still unclear to me, so let me ask again: 
will this feature (SID history compression) be supported?

Regarding 'first submission' task: I'm all for it! Actually, I've been 
studying Samba for some time now, mainly by reading the wiki, Windows 
protocols docs, looking at the code and the tests and trying hard to 
build some kind of the 'lab domain'. I would say that the entry 
threshold is high enough, so such an initial task from Samba masters 
would be very useful.

Thank you very much!
