389 DS DNA Plugin / Replication failing on GSSAPI
Last modified: 2012-06-20 03:14:08 EDT
This bug is created as a clone of upstream ticket: https://fedorahosted.org/389/ticket/12 https://bugzilla.redhat.com/show_bug.cgi?id=755119 {{{ Description of problem: There appears to be a race failing when the DNA Plugin attempts to make a uid range replication request backed by gssapi. Version-Release number of selected component (if applicable): 389-ds-base-libs-1.2.10-0.5.a5.fc15.x86_64 389-ds-base-1.2.10-0.5.a5.fc15.x86_64 How reproducible: 100% Steps to Reproduce: 1. Install IPA Server (ipa-server-install) 2. Prepare Replica (ipa-replica-prepare replica-hostname) 3. Transfer resulting replica-hostname.gpg 4. Install Replica (ipa-replica-install replica-hostname.gpg) 5. kinit admin 6. Attempt to create new user (ipa user-add test) Actual results: ipa: ERROR: Operations error: Allocation of a new value for range cn=posix ids,cn=distributed numeric assignment plugin,cn=plugins,cn=config failed! Unable to proceed. Expected results: Expected new user to be added and range to be transferred. Additional info: }}}
Please add steps to reproduce/verify with just RHDS
(In reply to comment #1) > Please add steps to reproduce/verify with just RHDS Do a 2 master replication WAN test with both servers set up to do DNA and range requests - might be able to use the existing DNA test suite, just using WAN replication
Technical note added. If any revisions are required, please edit the "Technical Notes" field accordingly. All revisions will be proofread by the Engineering Content Services team. New Contents: Cause: Using replication with DNA to auto-generate UID numbers. Consequence: Adding users fails with error messages like this: Operations error: Allocation of a new value for range cn=posix ids,cn=distributed numeric assignment plugin,cn=plugins,cn=config failed Fix: DNA was using a too-short timeout value that was causing problems on networks with high latency (WANs, etc.). The fix was to use the correct timeout value specified in the replication configuration. Result: No errors adding users when using replication with DNA.
Tested DNA plugin with ranges o LAN. I didn't see any error messages. Hence marking the bug as verified.
