Hai ,  
I need to change the column names in the user source table because doing so causes the authentication to fail.

Is it **viable** to **modify** the table?How **am i able to** authenticate?

Thanks in advance,

Please provide more information. What you starting with, what changes you are making, and why, at the very least.

its not inserting the value to the appropriate field .(which one I newly added column into the user tabel)

# Get new user

userToGet = system.user.getNewUser("AcmeWest", "mTrejo")

# Add some contact info

contactInfo = {"[email":"mTrejo@acmewest.com](mailto:email%22:%22mTrejo@acmewest.com)","sms": "5551234"}  
userToGet.addContactInfo(contactInfo)  
userToGet.set("password", "thisIsMyPassword")

# Add New colmun for empid

userToGet.set("empid", "1000")

# Adds a user to the the AcmeWest usersource.

Well, that function isn't documented to support custom columns in a user source. The User class, while a PropertySet, has a static list of properties exposed. This is a database table. Use database methods to alter its content.
