Initial Comment:
Hello,

I use autofs with ldap maps to mount nfs groups dirs.
in my case, autofs handle /home .
if i go to /home , and press for exemple z<TAB to use bash completion, it make ldap request and try to mount all.results:


root at a12p51:~# cd /home
root at a12p51:/home# z<TAB>
zcat              zdiff             zeisstopnm        zfgrep            zic               zipgrep           zipsplit          zmore             zxpdf
zcav              zdump             zeitgeist-daemon  zforce            zip               zipinfo           zjsdecode         znew              
zcmp              zegrep            zenity            zgrep             zipcloak          zipnote           zless             zsoelim

And this fao all the result.
If i go to /home and press <TAB><TAB> this make aver 4000 request to ldap and make the server averloaded.

There is a solution to this problem?

Thank you!
Mike
