SQL SERVER AND HIBERNATE UPDATE DDL ISSUE -

i've been on problems hibernate ddl update tool , sql server. first of explain our application ddl update works on mysql, postgres or oracle.

let me explain happens:

we created in sqlserver users access same databases, in different schemas, example:

• users: user1, user2, user3
• user1 connects schema1
• user2 connects schema2

• user3 connects schema3

  the permissions granted these users are: db_datareader, db_datawriter, dbowner, public

  it works sometimes, doesn't

have guys ever experienced problem this?
