Fixed In Version: 389-ds-base-1.3.3.1-6.el7
Doc Type: Bug Fix
Doc Text:
Cause: When macro aci is dynamically added and if the aci's macro target dn is not normalized, the following operation that requires the aci could fail with Insufficient access since matching the target dn and the macro target dn fails since the code expects normalized macro target dn. Fix: Before setting the macro target dn, the dn is normalized. Result: Even if an aci that contains pre-normalized macro target dn is dynamically added, it's correctly used to evaluate the access rights.

Description Noriko Hosoi 2014-10-09 23:46:59 EDT
This bug is created as a clone of upstream ticket:
https://fedorahosted.org/389/ticket/47922

This is a reguression.

sample aci>
dn: <SUFFIX>
aci: (target="ldap:///ou=People, ($dn), <SUFFIX>") (targetattr!="userPassword")(targetfilter=(objectClass=nsManagedPerson)) (version 3.0; acl "Admin access to all users in this and lower domains"; allow (write,read,search) groupdn="ldap:///cn=Domain Administrators, ou=Groups, [$dn], <SUFFIX>";)

UserA in the groupdn fails to modify the attributes of UserB which has "objectClass: nsManagedPerson" and under ou=People,($dn),<SUFFIX>.  Both UserA and UserB share the same $dn.

The modify attempts returns Insufficient access.
ldap_modify: Insufficient access
ldap_modify: additional info: Insufficient 'write' privilege to the 'sn' attribute of entry 'uid=UserB,ou=people,($dn),<SUFFIX>'.

Restarting the server solves this problem and UserA is allowed to modify UserB's attributes.
Comment 3 Viktor Ashirov 2014-11-24 11:55:28 EST
$ rpm -qa | grep 389
389-ds-base-1.3.3.1-9.el7.x86_64
389-ds-base-debuginfo-1.3.3.1-9.el7.x86_64
389-ds-base-libs-1.3.3.1-9.el7.x86_64

1. I did a fresh install of DS, added test entries.
2. Checked that UserA cannot modify UserB sn attribute:
$ ldapmodify -h localhost:389 -D "cn=UserA,ou=People,dc=subdomain1,dc=hostedcompany1,dc=example,dc=com" -w Secret123 
dn: cn=UserB,ou=People,dc=subdomain1,dc=hostedcompany1,dc=example,dc=com
changetype: modify
replace: sn
sn: UserB_modified_by_UserA

modifying entry "cn=UserB,ou=People,dc=subdomain1,dc=hostedcompany1,dc=example,dc=com"
ldap_modify: Insufficient access (50)
	additional info: Insufficient 'write' privilege to the 'sn' attribute of entry 'cn=userb,ou=people,dc=subdomain1,dc=hostedcompany1,dc=example,dc=com'.

3. Added aci to ou=people,dc=subdomain1,dc=hostedcompany1,dc=example,dc=com:
aci: (target="ldap:///ou=People, ($dn), dc=example,dc=com") (targetattr!="userPassword")(targetfilter=(objectClass=inetOrgPerson)) (version 3.0; acl "Admin access to all users in this and lower domains"; allow (write,read,search) groupdn="ldap:///cn=Domain Administrators, ou=Groups, [$dn], dc=example,dc=com";)

4. Checked that UserA can modify UserB sn attribute:
$ ldapmodify -h localhost:389 -D "cn=UserA,ou=People,dc=subdomain1,dc=hostedcompany1,dc=example,dc=com" -w Secret123 
dn: cn=UserB,ou=People,dc=subdomain1,dc=hostedcompany1,dc=example,dc=com
changetype: modify
replace: sn
sn: UserB_modified_by_UserA
modifying entry "cn=UserB,ou=People,dc=subdomain1,dc=hostedcompany1,dc=example,dc=com"

$ ldapsearch -o ldif-wrap=no -LLL -x -H ldap://localhost:389 -D "cn=Directory Manager" -w Secret123 -b dc=example,dc=com "(cn=UserB)" sn
dn: cn=UserB,ou=People,dc=subdomain1,dc=hostedcompany1,dc=example,dc=com
sn: UserB_modified_by_UserA

Dynamically added macro aci was evaluated without server restart. Hence marking this bug as VERIFIED.
