Savita,

Log in to the server using the user name, you are using in your ODBC
connection.  Make sure you can change directory to
/datatel/development/coldev if it is not already the home directory.  Define
unidata environment variable it is already not in the login script. Use udt
command to go into unidata if the login script does not do it.  Use command
like "SQL SELECT * FROM filename" to make sure you have privilege etc. on
the file.

Then try ODBC from Access.

Regards
Kafsat

This should be in an FAQ somewhere...

The user who runs unirpcd must be a member of the group that owns the 
database. I believe user permissions are ignored.

For example...

unirpcd is running as root.
the database you're trying to access is /datatel/development/coldev
the permissions on coldev are Owner:datatel Group:cdev Perms:770

root MUST be a member of the "cdev" group.

Note the lack of access control unless you set up good views and privileges!

Hope that helps,

Louis
