[Bug 783836] Re: slapd syncrepl failing using SASL

[James Page]

** Description changed:

  SRU INFORMATION:
  
  IMPACT:
  Replication failure occurs after some time when using TLS/LDAPS with SASL/GSSAPI; this normally happens when under high throughput.
  
  FIX:
  Cherry picked from upstream commit:
    http://www.openldap.org/devel/gitweb.cgi?p=openldap.git;a=commitdiff;h=f32f1a45d4e4f3259e33cedc3571c27787add409
  
  Very small change.
  
- This issue has already been fixed in 2.4.24 (in Natty) so impacts Lucid and Maverick.  The upstream bug report contains commentary on the effectiveness of the fix.

  Same deal with slapd 2.4.23 from maverick
  
  Turns out to be OpenLDAP ITS#6639 and is fixed in the 2.4.24 release
