Protecting file services provided by LFS/ESA

If LAN File Services/ESA (LFS/ESA) Release 1 is installed, you can use the LFSCLASS class to control user access to LAN File Services.

The resource name contains two parts:

A data set name
A workstation directory name

The two parts are separated with a colon. The workstation directory name contains the directory name and at least one subdirectory, with a backslash (\) before every subdirectory name. A maximum length of 246 characters is supported.

Here is an example of using the LFSCLASS class:

Create a profile in LFSCLASS class:

RDEFINE LFSCLASS MVS.DATASET.NAME:\DIR1\SUBDIR

If you have not already done so, activate the LFSCLASS class:
```
SETROPTS CLASSACT(LFSCLASS)
```

Note: RACF® supports the backslash (\) character for use with the LFSCLASS class. However, you might need to change your VTAM® translation table to support the backslash (\). For more information, refer to z/OS TSO/E Programming Guide for your operating system.
