Description Rich Megginson 2011-08-25 17:40:23 UTC

This bug is targeted for DSIPA21 but fixed after 1.2.9.6 so not included in the rebase, so cloning.

+++ This bug was initially created as a clone of Bug #732541 +++

Description of problem:
When adding an AutoMember definition, it is possible to receive an error 32 because the plugin is searching for children prior to the definition existing.

Error Message:
auto-membership-plugin - automember_parse_config_entry: Error searching for child rule entries for config "cn=hostgroup,cn=automember,cn=etc,dc=example,dc=com" (err=32)

How reproducible:
The problem seems to manifest itself when you use 2 separate LDIFs.  
1st LDIF contains the cn=config modification to point at cn=config
2d LDIF contains the cn=Hostgroup/cn=Group,cn=automember,cn=etc,$SUFFIX

Steps to Reproduce:
1. Install FreeIPA
2. Insert modification to cn=config to point to cn=automember,cn=etc,$SUFFIX
3. Insert modification to add cn=Hostgroup/cn=Group,cn=automember,cn=etc,$SUFFIX
  
Actual results:
Error Message:
auto-membership-plugin - automember_parse_config_entry: Error searching for child rule entries for config "cn=hostgroup,cn=automember,cn=etc,dc=example,dc=com" (err=32)

Expected results:
Expected that the definitions get created successfully without having to search for children prior to their own existence.

--- Additional comment from nkinder on 2011-08-24 13:18:23 EDT ---

To reproduce without having to install/setup FreeIPA, do the following:

- Run setup-ds.pl to create a new DS instance with a suffix of 
  'dc=example,dc=com'.

- Use ldapmodify to apply the operations in ldif1.ldif (attached).

- Do a 'service dirsrv restart' to apply the config area change from ldif1.ldif.

- Use ldapmodify to apply the operations in ldif2.ldif (attached).  This will
  fail with an err=53.

The fix should cause the second ldif to apply with no errors.
