Re: [Samba] join samba 4.5.12 to samba 4.1.13 failed




Hai, 

I must ask first, did you check the "before and after the update" steps,
found here https://wiki.samba.org/index.php/Updating_Samba

Your error looks like and it might have todo with samba 4.1.x and ntvfs: 
https://wiki.samba.org/index.php/Migrating_the_ntvfs_File_Server_Back_End_to_s3fs 

Last, if the join keeps failing, upgrade the DC with FSMO roles. 
Change ntvfs to s3fs and the join of DC3. 

Thats only what i can suggest, maybe Rowland has a better option but these are old bugs your hitting. 
It might have todo with the ntvfs, or can be corrupted DB, or slow network connection, or AD DB size. (total number of object) 
And that in combination with samba 4.1. upgrade to 4.5 is a big step.

The config shown looks ok, so i dont think is a config/setup error.
