Re: [Samba] DN lists have different size: 4065 != 4029




Hai, 
 
Now, differences is fine, but can you see if one of the 2 servers is correct, and for that it might be handy to share the output. 
 
You can push the good DB to the other DC. ( a forced replication ) 
 
And i can understand why you upgrade ...  
Did you see :  
 
samba-tool domain schemaupgrade --help
Usage: samba-tool domain schemaupgrade [options]
Domain schema upgrading
Options:
  -h, --help            show this help message and exit
  -H URL, --URL=URL     LDB URL for database or target server
  -q, --quiet           Be quiet
  -v, --verbose         Be verbose
  --schema=SCHEMA       The schema file to upgrade to. Default is (Windows)
                        2012_R2.

 
The "Default" in samba 4.10.x is 2012R2..  
but show the output, we will think of something to fix it :-) 
 
 
Greetz,

Hello guys,


Why did you upgrade the schema to '69' ?

That is the schema from 2012R2 and is still marked as experimental. 

I do not know why I did this update. Maybe I thought I could use DC as 2012R2. <sad>


Could you run :   
samba-tool ldapcmp ldap://dc3 ldap://dc4 --filter=cn,CN,dc,DC 
And compair that output? 

I made the comparison. It has a jumble of differences.


Can I do a schema downgrade?
