Scheduled Service Change: Upgrade of LDAP Directory (SunOne)
Some applications may be unable to use directory services during the upgrade. Applications connect using DNS round robin. If applications get connected to the ds2.directory.cornell.edu server, they will be affected.\n
There is no workaround for this issue
The LDAP directory (SunOne) will be upgraded from 6.3 on RHEL4 to 7.0 on RHEL5.
