The trusted roots file contains certificates for other servers that the local server treats as trusted when properly added to the system. A trusted roots file is accessible by the local server (Adaptive Server Enterprise) in:
if $SYBASE_CERT is defined. Otherwise it is in:
$SYBASE/$SYBASE_ASE/certificates/servername.txt (for UNIX)
%SYBASE%\%SYBASE_ASE%\certificates\servername.txt (for NT)
where servername is the name of the current Adaptive Server.
