Projects enable you to keep track of system resource usage by user, group, or role.
Because of error or oversight, no projects are available to choose. Check project files, NIS maps, or LDAP for possible corruption. If you have not already populated appropriate files or maps, see "Projects and Tasks" in System Administration Guide: Resource Management and Network Services, on docs.sun.com.
For LDAP, see also Solaris Management Console Help->About the Toolbox Editor->"To Manage LDAP."
