Fix text

The IAO will ensure that procedures are in place to control Logonids with the READALL attribute. The READALL privilege is available for actual auditing of system data. It gives the capability of looking at every data set on the system despite the data set rules. Its use is strongly discouraged. Always grant access through the use of standard data set access rules. Under no circumstances will the privilege be used as a convenience to the person maintaining the rule sets. Only use this privilege when absolutely necessary, and only give it to auditors. Remove the privilege once the audit is complete. Fully document the granting and revoking of the access.
