1 % CONNECT Connects to an LTPDA repository and returns the connection object.

4 % DESCRIPTION: Connects to an LTPDA repository and returns the connection
5 % object. The provided credentials are stored in a persistent utility, and
6 % reused when a connection to the same database and server is requested.
7 %
8 % If credentials for the requested database and server are not given, and are
9 % not in the utility, the user is prompted for the missing informations.
10 % Credentials are set to expire and to be entered again after a time defined
11 % in the LTPDA user preferences.
