RHEL 5.6 automount Solaris NIS maps didn't work as expected

jzwnxh — Thu, 05 Sep 2013 11:55:37 GMT

NIS-Master: SUN Solaris
NIS-Slave: RHEL 5.6

NIS-Client ( bound on NIS-Slave !) ; RHEL 5.6

automount is only working partially.

It doesn't mount auto.master entries at all - which are NIS maps too ?!
Any ideas, comments, hints tips ?!

Regards

What does "grep ^automount /etc/nsswitch.conf" report?

Have you modified the MASTER_MAP_NAME setting in /etc/sysconfig/autofs?

Is your NIS auto.master map named exactly "auto.master"? Or is it actually something else, like "auto_master" or "auto.master.byname"? (See "ypcat -x" for map nickname translation: by default, RHEL 5.x does not have a nickname for the automounter map, while Solaris might have one.)

Does the /etc/auto.master file have a matching uncommented "+auto.master" entry?

NIS automaster map is a solaris map named
ypcat auto.master    (from solaris node)
/etc/auto.sys    -rw,intr,hard,nosuid
auto.home        -rw,intr,hard,nosuid
auto.admin       -rw,intr,hard,nosuid
auto.direct

ypcat auto.master (from RHEL)
/etc/auto.sys    -rw,intr,hard,nosuid
auto.admin       -rw,intr,hard,nosuid
auto.direct
auto.home        -rw,intr,hard,nosuid

Changing BROWSE_MODE in /etc/sysconfig/autofs back to default ( deactivate BROWSE_MODE="no" !)
# BROWSE_MODE - maps are browsable by default.
#BROWSE_MODE="no"

let you see the Solaris automounter NIS maps.

Problem now occurs, that I can't step into the seen directories with cd:

No such file or directory
