Command line authentication requires a CSC user name and IDA password. Please note, that the IDA password is not the same as the CSC password. The IDA password is sent in an e-mail upon creation of the IDA profile.
The iinit command stores the user's password weakly encrypted into ".irods/.irodsA" in the user's home directory. The user must look after the security of the file in question. It is recommended to use the iexit full command, which removes the "irods/.irodsA" file, when ending the command line session. Connection between command line commands and the server is not allowed.
