<br>
Hi all,<br>
<br>
I'm just doing a migration from a gpfs cluster with samba/ctdb to CES protocol nodes. The old ctdb cluster uses rid as idmap backend. Since CES officially supports only autorid, I tried to choose the right values for the idmap ranges / sizes to get the same
IDs but was not successful with this.<br>
<br>
The old samba has a range assigned for their Active directory (idmap config XYZ : range = 1000000-1999999)<br>
<br>
My idea was to set autorid to the following during mmuserauth create:<br>
<br>
idmap config * : backend = autorid<br>
idmap config * : range = 200000-2999999<br>
idmap config * : rangesize = 800000<br>
<br>
With that it should use the first range for the builtin range and the second should then start with 1000000 like in the old rid config.<br>
<br>
Sadly, the range of the domain is the third one:<br>
<br>
/usr/lpp/mmfs/bin/net idmap get ranges<br>
RANGE 0: ALLOC<br>
RANGE 1: S-1-5-32<br>
RANGE 2: S-1-5-21-123456789-123456789-123456789<br>
<br>
Does anyone have an idea how to fix this, maybe in a supported way and without storing the IDs in the domain?<br>
<br>
Further on, does anyone use rid as backend, even if not officially supported? Maybe we could file a RPQ or sth. Like this.<br>
<br>
<br>
Mit freundlichen Grüßen / Best Regards<br>
