HP-UX Directory Server release notes HP-UX Directory Server Version 8.1 (B.08.10.04) (5900-2440, November 2012)

5 Limitations and restrictions
This section lists problems and limitations known to HP at time of publication.
• Windows Sync is not qualified for B.08.10.04
• To enable core file dumps of ns-slapd and related processes when aborting, system changes
are required prior to installation
By default for security reasons, processes that acquire a higher user privilege, such as the
ns-slapd daemon, are not dumped to a core file when aborting. (A process's privilege
escalation is evident by presence of the PS_CHANGEDPRIV flag in the pst_status structure
returned from pstat_proc().) To enable generation of core files when such processes abort
abnormally, you must manually adjust HP-UX system parameters prior to installing the HP-UX
Directory Server.
On HP-UX 11i v3 systems, use the coreadm tool, as documented in the coreadm(1M) and
coreadm(2) man pages. This tool enables (and disables) core file writing by setuid process.
On HP-UX 11i v2 systems, use the following command to enable the process to dump to a
core file:
$ echo 'dump_all/W 1' | adb -w -o /stand/vmunix /dev/kmem
This results in the following output:
dump_all: 0 = 1
On HP-UX 11i v2 systems, after the core file is generated, you should disable processes from
being dumped to a core file. Use the following command:
$ echo 'dump_all/W 0' | adb -w -o /stand/vmunix /dev/kmem
This results in the following output:
dump_all: 1 = 0
If you forget to reset dump_all, it will be reset to zero at the next system reboot. On HP-UX
11i v3 systems, you need not reset dump_all. Because the dump_all is set on the process,
the setting returns to the default once the process is gone.
• The Administration Server cannot run with the user ID root.
The value you enter for the System User in the setup-ds-admin.pl script dialog sets the
user ID for the Directory Server and the Administration Server. If you configure root for the
System User name, the Administration Server cannot run. The Administration Server runs as
a component of the Apache server; the HP-UX Apache-based Web Server does not allow the
Apache server to run with the user ID root.
The System User name in the setup-ds.pl script dialog is not affected by this restriction.
The setup-ds.pl script configures the user ID for the Directory Server but not for the
Administration Server. However, HP recommends that you do not run the Directory Server
with the user ID root.
• Selecting the Configuration tab results in Java exception errors.
When a nonprivileged user logs into the Directory Console and selects the Configuration tab,
the Directory Console displays Java exception errors.
