Full_Name: Quanah Gibson-Mount Version: 2.4.45 OS: Linux URL: ftp://ftp.openldap.org/incoming/ Submission from: (NULL) (47.208.148.239) If you incorrectly configure slapo-rwm so that it has an invalid mapping, slapd will crash after a search is performed against the mapped base. For example: rwm-rewriteRule "(.+,)?dc=example2,[ ]?dc=com$" "$1dc-example, dc=com" rwm-rewriteRule "(.+,)?dc=example2,dc=com$" "$1dc-example,dc=com" (note that it has dc-example,dc=com instead of dc=example,dc=com) It might be helpful? to parse the rewrite rules for validity, but that may be difficult to do.
