If I have rewrite rules like this:
23 olcOverlay={1}rwm,olcDatabase={3}hdb,cn=config
objectClass: olcOverlayConfig
objectClass: olcRwmConfig
olcOverlay: {1}rwm
olcRwmRewrite: {0}rwm-rewriteEngine on
olcRwmRewrite: {1}rwm-rewriteContext searchFilter
olcRwmRewrite: {2}rwm-rewriteRule "(.*\\()uid=sapr3(\\).*)" "$1uid=dlmsapr3$2"
olcRwmRewrite: {3}rwm-rewriteRule "(.*\\()uid=sdb(\\).*)" "$1uid=sdb$2"
olcRwmRewrite: {4}rwm-rewriteRule
"(.*\\()uid=sapadm(\\).*)%2"%2$1uid=dlmsapadm$2"
olcRwmRewrite: {5}rwm-rewriteRule "(.*\\()uid=sapmnt(\\).*)" "$1uid=sapmnt$2"
olcRwmRewrite: {6}rwm-rewriteRule "(.*\\()uid=[a-z0-9]{3}adm(\\).*)"
"$1uid=dlmsidadm$2"
olcRwmRewrite: {7}rwm-rewriteRule "(.*\\()uid=sqd[a-z0-9]%3%3}(\\).*)"
"$1uid=dlmsqdsid$2"
olcRwmRewrite: {8}rwm-rewriteRule "(.*\\()uid=ora[a-z0-9]{3}(\\).*)"
"$1uid=dlmorasid$2"
olcRwmRewrite: {9}rwm-rewriteRule "(.*\\()uid=sap[a-z0-9]{3}(\\).*)"
"$1uid=dlmsapr3$2"
olcRwmRewrite: {10}rwm-rewriteRule "(.*\\()uid=sap[a-z0-9]{3}db(\\).*)"
"$1uid=dlmsapr3db$2"
olcRwmRewrite: {11}rwm-rewriteRule "(.*\\()uid=db2[a-z0-9]{3}(\\).*)"
"$1uid=dlmdb2sid$2"
olcRwmRewrite: {12}rwm-rewriteRule "(.*\\()uid=db2[a-z0-9]{3}ap(\\).*)"
"$1uid=dlmdb2sid$2"
then the ninth rule / statent f failes to escape. In this example ora*** get's
not correctly rewritten to dlmora***: See loglevel trace:
543b711d ==> rewrite_rule_apply rule='(.*\()uid=sapr3(\).*)'
string='(&(objectClass=dynamicObject)(entryExpireTimestamp<=20141013062840Z))'
[1 pass(es)]
543b711d ==> rewrite_rule_apply rule='(.*\()uid=sdb(\).*)'
string='(&(objectClass=dynamicObject)(entryExpireTimestamp<=20141013062840Z))'
[1 pass(es)]
543b711d ==> rewrite_rule_apply rule='(.*\()uid=sapadm(\).*)'
string='(&(objectClass=dynamicObject)(entryExpireTimestamp<=20141013062840Z))'
[1 pass(es)]
543b711d ==> rewrite_rule_apply rule='(.*\()uid=sapmnt(\).*)'
string='(&(objectClass=dynamicObject)(entryExpireTimestamp<=20141013062840Z))'
[1 pass(es)]
543b711d ==E E rewrite_rule_apply rule='(.*\()uid=[a-z0-9]{3}adm(\).*)'
string='(&(objectClass=dynamicObject)(entryExpireTimestamp<=20141013062840Z))'
[1 pass(es)]
543b711d ==> rewrite_rule_apply rule='(.*\()uid=sqd[a-z0-9]{3}(\).*)'
string='(&(objectClass=dynamicObject)(entryExpireTimestamp<=20141013062840Z))'
[1 pass(es)]
543b711d ==> rewrite_rule_apply rule='(.*\\()uid=ora[a-z0-9]{3}(\\).*)'
string='(&(objectClass=dynamicObject)(entryExpireTimestamp<=20141013062840Z))'
[1 pass(es)]
543b711d ==> rewrite_rule_apply rule='(.*\()uid=sap[a-z0-9]{3}(\).*)'
string='(&(objectClass=dynamicObject)(entryExpireTimestamp<=20141013062840Z))'
[1 pass(es)]
543b711d ==> rewrite_rule_apply rule='(.*\()uid=sap[a-z0-9]{3}db(\).*)'
string='(&(objectClass=dynamicObject)(entryExpireTimestamp<=20141013062840Z))'
[1 pass(es)]
543b711d ==> rewrite_rule_apply rule='(.*\()uid=db2[a-z0-9]{3}(\).*)'
string='(&(objectClass=dynamicObject)(entryExpireTimestamp<=20141013062840Z))'
[1 pass(es)]
543b711d ==> rewrite_rule_apply rule='(.*\()uid=db2[a-z0-9]{3}ap(\).*"727
string='(&(objectClass=dynamicObject)(entryExpireTimestamp<=20141013062840Z))'
[1 pass(es)]
If I insert a dummy statement like this:
olcRwmRewrite: {0}rwm-rewriteEngine on
olcRwmRewrite: {1}rwm-rewriteContext searchFilter
olcRwmRewrite: {2}rwm-rewriteRule "(.*\\()uid=sapr3(\\).*)" "$1uid=dlmsapr3$2"
olcRwmRewrite: {3}rwm-rewriteRule "(.*\\()uid=sdb(\\).*)" "$1uid=sdb$2"
olcRwmRewrite: {4}rwm-rewriteRule "(.*\\()uid=sapadm(\\).*)"
"$1uid=dlmsapadm$2"
olcRwmRewrite: {5}rwm-rewriteRule "(.*\\()uid=sapmnt(\\).*)" "$1uid=sapmnt$2"
olcRwmRewrite: {6}rwm-rewriteRule "(.*\\()uid=[a-z0-9]{3}adm(\\).*)"
"$1uid=dlmsidadm$2"
olcRwmRewrite: {7}rwm-rewriteRule "(.*\\()uid=sqd[a-z0-9]{3}(\\).*)"
"$1uid=dlmsqdsid$2"
olcRwmRewrite: {8}rwm-rewriteRule "(.*\\()uid=ora[a-z0-9]{3}(\\).*)"
"$1uid=dlmorasid$2"
olcRwmRewrite: {9}rwm-rewriteContext placeHolder alias searchFilter
olcRwmRewrite: {10}rwm-rewriteRule "(.*\\()uid=sap[a-z0-9]{3}(\\).*)"
"$1uid=dlmsapr3$2"
olcRwmRewrite: {11}rwm-rewriteRule "(.*\\()uid=sap[a-z0-9]{3}db(\\).*)"
"$1uid=dlmsapr3db$2"
olcRwmRewrite: {12}rwm-rewriteRule "(.*\\()uid=db2[a-z0-9]{3}(\\).*)"
"$1uid=dlmdb2sid$2"
olcRwmRewrite: {13}rwm-rewriteRule "(.*\\()uid=db2[a-z0-9]{3}ap(\\).*)"
"$1uid=dlmdb2sid$2"
then the escapes are working properly.
Sometimes this occurs with the last rule too.
I first tried with 2.4.26 (standard version in SLES11 SP3) and now with 2.4.40.
