[Samba] question about --use-rfc2307

[Eduardo Sotomayor]

I have promoted a samba active directory server using the --use-rfc2307 option, my question is, after doing that is it necessary to follow these instructions?


https://wiki.samba.org/index.php/Using_RFC2307_on_a_Samba_DC#Extending_the_Schema_for_NIS_Extensions

I ask because I am getting the following




server01:/home/eduardo
# samba-tool fsmo show | grep SchemaMasterRole

SchemaMasterRole
owner: CN=NTDS Settings,CN=SERVER01,CN=Servers,CN=Default-First-Site-Name,CN=Sites,CN=Configuration,DC=sienic,DC=site


server01:/home/eduardo
# systemctl stop samba.serviceserver01:/home/eduardo # cp
/usr/local/samba/share/setup/ypServ30.ldif /tmp/


server01:/home/eduardo
# sed -i -e 's/${DOMAINDN}/DC=sienic,DC=site/g'          -e 's/${NETBIOSNAME}/server01/g'          -e 's/${NISDOMAIN}/sienic/g'          /tmp/ypServ30.ldif


server01:/home/eduardo
# ldbmodify -H /usr/local/samba/private/sam.ldb /tmp/ypServ30.ldif
--option="dsdb:schema update allowed"=true

ERR: (Entry

DN CN=ypServ30,CN=RpcServices,CN=System,DC=sienic,DC=site at block before line

and if I do the following



server01:/home/eduardo
# ldbsearch --url=/usr/local/samba/private/sam.ldb -b
"CN=Schema,CN=Configuration,DC=sienic,DC=site" >
/home/eduardo/schema.ldif




and then check the schema.ldif file I can find the 

CN=PosixAccount,CN=Schema,CN=Configuration

when yo say
"This automatically enables RFC2307 and installs the NIS Extensions"

this also means that
"extending the schema for NIS Extensions"
are the same thing or they give the same result?
I am a little confuse here, thanks
