Capitalization is not important in the Samba configuration file except in locations where it would confuse the underlying operating system. For example, let's assume that you included the following option in a share that pointed to
/export/samba/simple :
PATH = /EXPORT/SAMBA/SIMPLE
Samba would have no problem with the
path
configuration option appearing entirely in capital letters. However, when it tries to connect to the given directory, it would be unsuccessful because the Unix filesystem in the underlying operating system
is case sensitive. Consequently, the path listed would not be found and clients would be unable to connect to the share.
