This bug occurs during an upgrade from Solaris 10 Hardware 2 release to the current Solaris 10 5/09 release.
In the Solaris 10 Hardware 2 release, the name_service.xml file for any name service, such as NIS, NIS+, FILES, or LDAP is as follows:
# ls -l name_service.xml lrwxrwxrwx 1 root root 10 Apr 10 16:26 name_service.xml -> ns_files.xml
If the name service is NIS, the name_service.xml file links to ns_files.xml. However, the contents of the ns_files.xml are the same as ns_nis.xml.
# cat /etc/release Solaris 10 3/05 HW2 s10s_hw2wos_05 SPARC Copyright 2005 Sun Microsystems, Inc. All Rights Reserved. Use is subject to license terms. Assembled 26 September 2005 # cd /var/svc/profile # ls -l name_service.xml ns_files.xml ns_nis.xml lrwxrwxrwx 1 root other 12 May 21 04:06 name_service.xml -> ns_files.xml -r--r--r-- 1 root sys 779 May 21 04:25 ns_files.xml -r--r--r-- 1 root sys 779 Jan 21 2005 ns_nis.xml # # diff ns_files.xml ns_nis.xml # diff name_service.xml ns_nis.xml
In the above output, the ns_nis.xml and ns_files.xml files are the same. This means that the name_service.xml file symbolically links to the wrong name service file. The name_service.xml file links to ns_files.xml. Instead, the name_service.xml file should link to the ns_nis.xml.
The fix for CR 6411084, the SUNWcsr install or postinstall script, creates the correct link only if name_service.xml is not a link file. If name_service.xml is already a symbolic link file, as in the Solaris 10 Hardware 2 release, the fix for CR 6411084 will not work.
After an upgrade from Solaris 10 Hardware 2 to the current Solaris 10 5/09 release, the following message is displayed on the console or logged in the messages file:
Oct 23 12:18:45 vt2000a automount: [ID 366266 daemon.error] can't read nis map auto_master: can't communicate with ypbind - retrying
Also, the /network/nis/client:default service is offline.
Workaround: Choose one of the following workarounds:
Workaround 1: Before an upgrade, remove the /var/svc/profile/name_service.xml file.
Workaround 2: After an upgrade, change the /var/svc/profile/name_service.xml link to the correct ns_<xxx>.xml file, based on the name service.
