The issue seems to be caused by a change in the default security mode of the Samba client installed on the RaspberryPi. Apple Time Capsule appears to only support the NTLM password hashing method and, apparently, this is no longer what the client provides (interestingly enough, the
mount.cifs man page still states that NTLM is the default option though).
In order to force the client to set the security mode to what's required by Time Capsule, you need to explicitly set a relevant flag. Your
/etc/fstab entry might therefore look like the following:
//192.168.1.1/Time-Capsule /mnt/TimeCapsule cifs credentials=[your_TimeCapsule_credentials_path],file_mode=0777,dir_mode=0777,rw,sec=ntlm 0 0
The most important bit is the
sec=ntlm option and this is what should do the trick. However, please bear in mind that for security reasons NTLM is no longer recommended by Microsoft who originally designed it.
And just to confirm I have had exactly the same problem with my Time Capsule since December 2013 when I ran an APT update that included
samba-common-bin package changes. All of them were what seemed like very minor updates though: from version 3.6.6-6+deb7u1 to 3.6.6-6+deb7u2.
Fred has asked about the
cifs-utils version and in my case it is currently 2:5.5-1. I'm not sure if this is relevant but this particular package did not get updated in that round of Samba changes.
