No access to home folder via SMB


I have one user which suddenly can not access it’s own home directory via SMB from a windows client any longer. All shares are still working. All other users can still connect to their home folders via \\<ip-of-the-server\<username> except this one user.

I did not find anything in the log files that explain why this user can not access it’s home folder.

Any ideas where to search for a solution?
