Hello everyone, I restored a library from a tape backup, after the restore the group profile TSTOWNER lost all the authorities over the library and the objects in this library. Could somebody, please, tell me how can I give a group profile its authorities back ? I've tried everything I know and I can't get it done. I tried with WRKOBJ command, then F6 to add a new user, this allow me to add the user TSTOWNER but all users in the group profile still without authority over the library and the objects. I've tried EDTOBJAUT and it is the something, I tried GRTOBJAUT and doesn't work either. I solved the problem, temporary, giving authority over all objects in the library to one of the users in that group using GRTOBJAUT command, but I can't believe I have to do this for each user in the group. This is what I have for the library I restored: Object User Group Authority *GROUP CCPOWNER *ALL *GROUP QPGMR *ALL *PUBLIC *EXCLUDE If I add the user TSTOWNER I get: Object User Group Authority *GROUP CCPOWNER *ALL *GROUP QPGMR *ALL TSTOWNER *USE *PUBLIC *EXCLUDE I think my problem will be solved if I get: Object User Group Authority *GROUP CCPOWNER *ALL *GROUP QPGMR *ALL *GROUP TSTOWNER *USE *PUBLIC *EXCLUDE How can I get the list above ? or Do I am hallucinating and this can't be done?. Our security guy have left the company and my boss want me to take the challenger, I am reading the Basic System Security and planning book and I haven't found anything that help me with this problem and other issues I have found in our system security. There is another book that you recommend ?. Please, any help will be great appreciated. Nilda Mejias. System Development Collectcorp Inc.
