I am using Samba 1.9.17p2 with FAST_SHARE_MODES (Solaris 2.5). The default permissions on the SHARE_MEM_FILE are 0666. Does anybody know why this is and what the implications would be if a user corrupted this file? I noticed in the source that there is a possibility to #define SECURE_SHARE_MODES (line 394 shmem.c) to change the permissions to 0600. Why is this not be the default? I presume something will break if I set it!
