When a user name or account name is composed entirely of numbers, 'setfacl' will not allow a domain prefix, so for example 'DOMAIN\123456' will not be possible.


By adding the prefix '\134'  (\134 is octal \) to the userid, e.g. DOMAIN\134123456, it is possible to use a numeric uid with the domain prefix.
DOMAIN\134123456 translates to DOMAIN\\123456 and setfacl/getfacl will then show it correctly as 'user:123456'.

A future update will allow '\\' instead '\134', and '\' corresponds to a literal backslash as is common everywhere else.


The '\' in the domain\userid 'DOMAIN\123456' can't be used, because '\' followed by three octal digits (0-7) in path, user or group names will be replaced by a character with that code.
'\123' in this example, 'DOMAIN\123456' translates to 'DOMAINS456' and is the incorrect userid.
