Full_Name: Emmanuel Lecharny Version: 2.4.45 OS: URL: ftp://ftp.openldap.org/incoming/ Submission from: (NULL) (82.123.98.139) There has been a change back in 2011 in the controls.c code : https://github.com/Symas/openldap/commit/4e32148ac59ba6b4f3acc79a3b782cd3... Line 1460 was : if ( ctrl->ldctl_value.bv_len ) { and was transformed to line 1516 : if ( BER_BVISNULL( &ctrl->ldctl_value )) { when it was expected to be : if ( !BER_BVISNULL( &ctrl->ldctl_value )) { as this control is not expecting any value. The consequence is that using this control in ldapsearch leads to an error being generated : "domainScope control value not empty"
