Automount issue with uppercase mountpoints

[Diego Julian Remolina <dijuremo@math.gatech.edu>]

Hi,

I run openldap 2.2.17 on a Solaris 9 machine.  All my clients (also
solaris 9) can
automount from auto_direct just fine as long as the mount points are
lowercase.  If the mount points are uppercase (like /opt/SUNWspro),
then the clients cannot mount.  Is this a Solaris issue or an
openldap issue.  I do not know how openldap handles upper/lower case
in the search filters so I hope you guys have the answer.

Here is what I see in the logs:

Note the search filter (cn=/opt/%s%u%n%wspro).

On the client I get a permission denied.  (It is not a permission
error as the client never hits the nfs server.  It only hits the
ldap server and then returns permission denied).  A simple fix for
it was to do the following on the client:
/etc/init.d/autofs stop
cd /opt
rmdir /opt/SUNWspro
mkdir /opt/sunwspro
ln -s sunwspro SUNWspro
then I changed the maps on the auto_direct.ldif map

Even though this hack works, I would like to find the right solution
for mount points that use uppercase letters.

Here is how my auto_direct maps looks like:
$ cat auto.direct.ldif
dn: nisMapName=auto_direct,ou=Automount,dc=math,dc=gatech,dc=edu
objectClass: top
objectClass: nisMap
nisMapName: auto_direct

dn:
cn=/opt/SUNWspro,nisMapName=auto_direct,ou=Automount,dc=math,dc=gatech,dc=ed
u
objectClass: nisObject
cn: /opt/SUNWspro
nisMapEntry:
-fstype=cachefs,-actimeo=10,-ro,-nosuid,cachedir=/export/cachefs,ba
ckfstype=nfs cauchy:/opt/SUNWspro
nisMapName: auto_direct

dn:
cn=/usr/local,nisMapName=auto_direct,ou=Automount,dc=math,dc=gatech,dc=edu
objectClass: nisObject
cn: /usr/local
nisMapEntry:
-fstype=cachefs,-actimeo=10,cachedir=/export/cachefs,backfstype=nfs
     cauchy:/export/local/local-Solaris
nisMapName: auto_direct

dn:
cn=/usr/local-ai,nisMapName=auto_direct,ou=Automount,dc=math,dc=gatech,dc=ed
u
objectClass: nisObject
cn: /usr/local-ai
nisMapEntry:
-fstype=cachefs,-actimeo=10,-ro,-nosuid,cachedir=/export/cachefs,ba
ckfstype=nfs cauchy:/export/local/local-ai
nisMapName: auto_direct

dn:
cn=/var/mail,nisMapName=auto_direct,ou=Automount,dc=math,dc=gatech,dc=edu
objectClass: nisObject
cn: /var/mail
nisMapEntry: -actimeo=0 math:/var/mail
nisMapName: auto_direct

Thanks for your help,
