[firebird-support] Inssuficient rights for operation....

[blumy2005]

Hello. I used Firebird 1.5.6 on server, a database with a role with full 
rights, and a user defined in ROLE, USER.
  
 I have a problem. In the network with a application, on different client 
station, login with the USER, all functions work OK.
  
 Only in one station, with XP, with USER login, a have this error, with 
insufficient sql rights for operation, no permission to read/select acces to 
TABLE.
  
 WHY THE DIFFERENT functionality? Same user, same rights on database.
