Hi, I started with LDAP just recently and I successfully built and implemented a custom schema. However there is one problem. I am required to add "userPasswordAtt" attribute to my custom schema which is similar to "userPassword" attribute in "inetOrgPerson" schema. This is what I tried so far: attributetype ( 1.28.7.2011.13.1 NAME 'userPasswordAtt' EQUALITY octetStringMatch SYNTAX 1.3.6.1.4.1.1466.115.121.1.40) It is basically a copy/paste of "userPassword" attribute. objectclass ( 1.28.7.2011.1.1 NAME 'eOskrbaPerson' DESC 'e-oskrba participant' SUP top STRUCTURAL MUST ( bidAtt $ uidAtt $ cnPatient $ userPasswordAtt ) MAY ( patientCoopFlagAtt $ patientsDoctorAtt $ eMailAtt $ dateOfBirthAtt $ sexAtt $ healthcareInstitutionAtt $ memberAtt $ mobilePhoneAtt $ experimentalGroupAtt ) ) But with this attribute I can not log in to phpLDAPadmin for example. It also doesn't cover password with dots on creation as it does with "userPassword". As far as I know "userPassword" is never defined as password in any schema, I am suspecting that it has to be somehow hardcoded (I also checked inheritance which goes all the way from core.schema). So far I also tried to avoid inheriting attributes from defined schemas. How can I use my custom attribute in the same way as "inetOrgPerson->userPassword"? Some pointers for future research would be greatly appreciated. Regards, Janez Barbic
