(ITS#8778) Phone numbers "-" and " " fail normalization
by h.b.furuseth＠usit.uio.no 26 Nov '17

Full_Name: Hallvard B Furuseth Version: 2.4.45, master OS: Linux x86_64 URL: Submission from: (NULL) (193.90.52.167) Submitted by: hallvard telephoneNumberNormalize() fails for a non-empty value of only spaces+hyphens. The validate function, printableStringValidate(), succeeds. They should agree. I'll make Normalize return one space. That seems the minimal change.

Does that mean it's not trivial to fix and will take some time? It's a last outstanding issue for a release, so I guess we have to find a work around until it's properly fixed? Thanks, Markus

Full_Name: Markus Junginger Version: mdb.master OS: Ubuntu URL: ftp://ftp.openldap.org/incoming/ Submission from: (NULL) (77.190.230.93) Read cursors may outlive a transaction to be renewed with another.

Full_Name: Thomas Quinot Version: slapd 2.X (Nov 22 2017 11:39:03) OS: Linux URL: ftp://ftp.openldap.org/incoming/quinot-171122.diff Submission from: (NULL) (2a02:2ab8:224:1:36e6:d7ff:fe09:66dd) If a tight ACL is globally defined for userPassword: access to attrs=userPassword by dn="cn=Manager,o=Local" write by self write by anonymous auth and there is a virtual naming context implemented using a relay backend with rwm overlay: database @BACKEND@ suffix "dc=example,dc=com" [...] database relay suffix o=OtherExample,c=US relay dc=example,dc=com overlay rwm rwm-suffixmassage "dc=example,dc=com" then an end-user's attempt to update her own password will fail with: err=53 text=unwilling to verify old password because at some point we attempt to apply the above ACL to the original (virtual) DN, but considering the resolved (real) DN for the user: 5a1553ea => acl_mask: access to entry "cn=Ursula Hampster,ou=Alumni Association,ou=People,o=OtherExample,c=US", attr "userPassword" requested 5a1553ea => acl_mask: to value by "cn=ursula hampster,ou=alumni association,ou=people,dc=example,dc=com", (=0)

IMHO it's not weird because for escaping the comma in DN string representation you need the first back-slash which you have to escape once more for config syntax. Ciao, Michael.

Hello, I confirm there is no bug, but the escaping is a little weird, as we need two \\ to escape the , character. Config sample: uri ldap://127.0.0.1/dc=test,dc=example,dc=com idassert-bind bindmethod="simple" binddn="cn=OUDOT\\, Clement,ou=users,dc=example,dc=com" credentials="secret" mode="legacy" flags="non-prescriptive" Thanks a lot to Michael Stroeder for his help. Clement.
