The entries in this file are similar to the httpd.translations file. There are two formats for file entries, as follows:
Map template result
Widelink template [@qtree] result
Any request that matches template is replaced with the result string given. Note that the result path for a "Map" entry must point to a destination within the share to which the client is connected. This is because the client has only been authenticated to that share; therefore access is limited to the same share for security reasons. A result path for a "Widelink" entry may point anywhere, thus the name "wide symlink" or widelink for short. Widelinks have these limitations-- the filer share on which the symlink resides must be enabled for wide symlinks, the CIFS client must support Microsoft's Dfs protocol, and the destination must be able to function as a Dfs leaf node. By using Dfs requests, the filer causes the client to authenticate with the destination and thus enforces security. To enable a filer share for "wide symlinks", use the "cifs shares -change" filer console command.
Both templates and results might (and usually do) contain wildcards (a star "*" character). The wildcard behaves like a shell wildcard in the template string, matching zero or more characters, including the slash ("/") character. In the result string, a wildcard causes text from the corresponding match in the template string to be inserted into the result.
The entries are examined in the order they appear in the file until a match is found or the lookup fails.
# Example Map symlink translations
Map /u/home/* /vol/vol2/home/*
Map /u/* /vol/vol0/*
The next example maps absolute symlinks that start with "/u/docs/" to go to the filer path "\\filer\engr\tech pubs". Note that widelink result paths use CIFS pathname syntax (backslashes are separators, spaces in path components are allowed, and so on).
# Example Widelink symlink translation
Widelink /u/docs/* \\filer\engr\tech pubs\*
The next example maps absolute symlinks that start with "/u/joe". Note that depending on how NFS mounts are set up, it is possible that there could be several absolute symlinks pointing to "/u/joe" which need to have differing destinations. The qtree in which a symlink resides can optionally be used to distinguish destinations. Thus, following an absolute symlink starting with "/u/joe" in qtree /vol/vol1/mixed takes the client to "\\filer\home\joe", while symlinks in other qtrees take the client to "\\filer\test tools\joe".
# Example Widelink symlink translations #
Widelink /u/joe/* @/vol/vol1/mixed \\filer\home\joe\* Widelink /u/joe/* \\filer\test tools\joe\*
Note that there is no theoretical reason why a wide symlink can't point to another filer or indeed any NT server, though it may be difficult to imagine the translated link making sense to the Unix client which created the original symlink.
# More Widelink examples
Widelink /u/joe/* @/vol/vol1/mixed \\myfiler2\users2\joe\*
Widelink /u/joe/* \\joe-PC\Program Files\*
