Handy SAS Usage Note for Troubleshooting UNIX Authentication

Whilst troubleshooting why LDAP based users couldn’t authenticate against a SAS Metadata Server configured for host authentication, I found this handy resource: SAS Usage Note 39891: Using PROC PERMTEST to diagnose UNIX host authentication issues in SASĀ® 9.2. The server in question already had correctly functioning LDAP host authentication via PAM, it was just that the SAS Metadata Server wasn’t able to authenticate the LDAP users. The usage note helped me fix the problem by leading me to the SASFoundation/SAS9.2/utilities/bin/sasauth.conf file where I found it had methods=pw instead of methods=pam (must have chosen the wrong options at install time). I actually didn’t need to run PROC PERMTEST this time but the usage note contains clear instructions on how to when required. Interestingly PROC PERMTEST doesn’t seem to appear in the Base SAS® 9.2 Procedures Guide.
