[Samba] Samba 4.14 upgrade schema to 2012_R2 error

[L.P.H. van Belle]

It should, but this is what i currently get. 
 
logged in on DC0 (FMSO master) 
samba-tool domain level show
Here i get : 
Forest function level: (Windows) 2008 R2
Domain function level: (Windows) 2008 R2
Lowest function level of a DC: (Windows) 2008 R2
 
samba-tool domain functionalprep --function-level=2012_R2
no errors
samba-tool domain level raise
no errors
 
ldbsearch -H $(smbd -b|grep private|awk '{ print $NF }')/sam.ldb -b cn=Schema,cn=Configuration,dc="$(hostname -d | cut -d. -f1)",dc="$(hostname -d | cut -d. -f2)",dc="$(hostname -d | cut -d. -f3)" -s base objectVersion
i get 69 and Windows Server 2012R2=69
 
samba-tool domain level show
and i get 
Forest function level: (Windows) 2008 R2
Domain function level: (Windows) 2008 R2
Lowest function level of a DC: (Windows) 2008 R2
 
logged in on DC1 
samba-tool domain level raise
All changes applied successfully!
ldbsearch -H $(smbd -b|grep private|awk '{ print $NF }')/sam.ldb -b cn=Schema,cn=Configuration,dc="$(hostname -d | cut -d. -f1)",dc="$(hostname -d | cut -d. -f2)",dc="$(hostname -d | cut -d. -f3)" -s base objectVersion
gives : 69
 
logged in on DC2
samba-tool domain level raise
All changes applied successfully!
 
ldbsearch -H $(smbd -b|grep private|awk '{ print $NF }')/sam.ldb -b cn=Schema,cn=Configuration,dc="$(hostname -d | cut -d. -f1)",dc="$(hostname -d | cut -d. -f2)",dc="$(hostname -d | cut -d. -f3)" -s base objectVersion
gives : 69
 
So all 3 AD-DC's are now  functionalpreped for function-level=2012_R2
 
Logged in again on DC0 (FSMO)
 
samba-tool domain level --forest-level=2012_R2 raise
ERROR: Forest function level can't be higher than the domain function level(s). Please raise it/them first!
 
samba-tool domain level --domain-level=2012_R2 raise
ERROR: Domain function level can't be higher than the lowest function level of a DC!
 
rebooted all servers. 
checked again, same results. 
 
Now i might be hitting an old bug since my AD exists since 4.1.x 
Not sure on that, if i have the time today i'll have a look at this. 
Or.. maybe Rowland knows ;-)

But in this new version (4.14.8) will it be possible to upgrade the domain level to 2012_R2?

If so, is there any procedure or will just the execution of the already known commands be enough?


Thanks
