Hi, I've started relying on undocumented exit codes for ldapmodify in places. These are defined in ldap.h, e.g.: #define LDAP_CONSTRAINT_VIOLATION 0x13 #define LDAP_TYPE_OR_VALUE_EXISTS 0x14 Presumably these are undocumented for good reason, but in practice can they be relied on not to change, at least as far as OpenLDAP 2 is concerned (additional exit codes are obviously not an issue). -- Liam Gretton liam.gretton(a)le.ac.uk HPC Architect http://www.le.ac.uk/its IT Services Tel: +44 (0)116 2522254 University of Leicester, University Road Leicestershire LE1 7RH, United Kingdom
