What SQL command do you run to create the ca_itrm user account ?
Execute the below statements to create ca_itrm user
IF NOT EXISTS (SELECT * FROM master.dbo.syslogins WHERE loginname = N'ca_itrm')
CREATE LOGIN [ca_itrm] WITH PASSWORD = 'NOT_changedR11'
GO
CREATE USER [ca_itrm] FOR LOGIN [ca_itrm] WITH DEFAULT_SCHEMA=[ca_itrm]
GO
GRANT CONNECT TO [ca_itrm]
Note: This is just another method of creating ca_itrm user.
