Re: Migration from NIS & Automount to LDAP & Automount under Redhat 7.2: something is broken?
I found that autofs is able to get the auto.master map without any help,
after tweaking the /etc/nsswitch.conf file; The /etc/init.d/autofs calls
the program ' /usr/lib/autofs/autofs-ldap-auto-master', generating
(correctly) the list of maps thay autofs shoudl retrieve:
[josevnz@linux0037 autofs-3.1.7]$
/usr/lib/autofs/autofs-ldap-auto-master
/home auto.home -rw,intr,rsize=4096,wsize=4096,acdirmin=40
/nb_apps auto.nb_apps -rw,intr,rsize=4096,wsize=4096,acdirmin=40
/data auto.data -rw,intr,rsize=4096,wsize=4096,acdirmin=40
I ran the migration tool to import every map i got on nis into the ldap
database, but looks like the autofs program is searching for something
else
Any ideas?
