This bug has been copied from bug #563956 and has been proposed
to be backported to 5.6 z-stream (EUS).
I can't pass the testcase bz563956:
ls: /nfs/abc2100: No such file or directory
failed to mount ldap direct mount after sizelimit set
for the full log you could refer to below:

btw, these failure occurs on s390x and ppc64, I can pass test on others arch:
verified autofs-5.0.1-0.rc2.143.el5_6.2 on ppc64 and s390x using the update testcase, results passed:

There's incomplete fix for bug 691311 that is the paged LDAP query doesn't work against ppc64 and s390x LDAP servers, so autofs will not support paged results from ldap server which set up on ppc64 or s390x arch, and if the ldap server use a separate server other than a ppc64 or s390x that will be ok. Developer recommend that file a new bug for this problem.
For the detailed information pls check below links:
So GSS guys, do you know if customer environment will involve ldap server
with ppc64 and s390x? I want to confirm the issue don't impact their production, thanks.
pasted these passed results using the updated testcase on autofs-5.0.1-0.rc2.143.el5_6.2:
I copy Ian's response from e-mail:
This needs a little more qualification.
We don't know if this would continue to be a problem if the openldap
server on these architectures supported paged LDAP queries. As it
happens the paged queries often do work in this case and that's why
autofs defines the missing LDAP functions if they aren't present. In
addition the openldap ldapsearch application "is" able to do paged
queries against these servers but the code is such a mess I haven't been
able to work out what they do differently yet.
So, the bottom line is that autofs currently doesn't work against
servers on these architectures and the openldap available on them
doesn't formally support this type of query. That's my motivation for
recommending we deal with this as a separate bug and go ahead with the
Could you consider the comment #21 and confirm with customer? If approval, we will deal with the errata as Ian's said.
change the status to verified against comment #17 and file a new bug 700896 to track the issue.
