Hi,
in order to be able to use IPA auth for Samba shares, I followed this
guide:
https://bgstack15.wordpress.com/2017/05/10/samba-share-with-freeipa-auth/
IPA and Samba are running on the same server, everything worked fine.
Actually, it still does, but since the upgrade from 7.4 to 7.5 (including
IPA 4.5.0->4.5.4, Samba 4.6.2->4.7.1 and sssd-1.15.2->1.60.0) file
browsing and copying is painfully slow on Mac, Windows and Linux (<10% of
the theoretical maximum). It "feels" as whether there is a timeout after
each file operation.
Nothing in the server logs. Client logs on Linux occasionally show a "CIFS
VFS: ioctl error in smb2_get_dfs_refer rc=-2". Reverting Samba back to
non-IPA auth (dedicated Samba accounts) gives expected performance (near
theoretical maximum).
I'm out of ideas on how to diagnose this. Any hints?
Mit freundlichen Gruessen/With best regards,
