Package: slapd
Version: 2.3.39-1
Severity: important
I've been running the same setup for a while - a master (x86_64) and two
syncrepl clients (x86_32): After some recent updates to the system,
I discovered this failure on both x86_(32|64)... It prevents package
updates from working, and destroys the ability to backup the local
databases.
$slapcat -b'dc=cobpli,dc=svl,dc=ibm,dc=com' -f /etc/ldap/ldif/slapcat.ldif

After much digging, I discovered the culprit:

database ldap
suffix "ou=bluepages,o=ibm.com"
directory /var/lib/ldap/bluepages
...
#
# Allow anyone to read the data locally
access to

...
# Cache the most common request form locally for improved performance
overlay pcache
proxycache bdb 10000 1 50 100
proxyattrset 0 mail
proxytemplate (&(objectClass=)(mail=)) 0 86400
directory /var/lib/ldap/bluepages
Commenting out the pcache overlay related entries does allow the slapcat
to continue... I think, but can not ensure that I've run slapcat since
adding the pcache overlay.

Ok, marking this bug as fixed in 2.4 then, thanks.

If you think this is a bug in pcache, please open a bug about this (or
upstream, if you prefer); I don't have a good test case for this overlay and
have never used it before, so I have no idea whether this could be a
documentation issue or if the overlay itself has bugs.
