slaptest conversion of acl regex's drops backslashes

Hi,

I used slaptest to convert a set of ACLs from standard to dynamic format using slaptest. I noticed that backslashes (used to escape characters) in regexes are silently dropped after conversion.

For example: access to dn.regex="^dc=\b\d{1,3}.\d{1,3}.\d{1,3}\b.in-addr.arpa,ou=dns,dc=example,dc=com$" by group.exact="cn=Admins,ou=Groups,dc=example,dc=com" write becomes: olcAccess: {xx}to dn.regex="^dc=\b\d{1,3}.\d{1,3}.\d{1,3}\b.in-addr.arpa,ou=dns,dc=example,dc=com$" by group/groupOfNames/member.exact="cn=admins,ou=groups,dc=noa,dc=gr" write

Is this expected behavior? Or am I doing something wrong?

Please advise.

Thanks, Nick
